      <description>&lt;p&gt;The internet economy in 2026 looks different from even a few years ago. Traditional freelancing still exists, but many people are building income around AI tools, automation systems, software products, content systems, remote specialized services, and digital products. Ordinary people—developers, creators, freelancers, and non-technical operators—can turn specific skills into income streams that range from side projects to full businesses.&lt;br&gt;
An opportunity is not the same as easy money. Results depend on skill level, niche selection, portfolio quality, sales ability, client type, geography, consistency, and demand. Some paths require almost no capital; others need time or modest tools. Some reward technical depth; others reward communication or creative judgment.&lt;br&gt;
This guide covers 10 distinct online hustles and digital business models that real people are exploring right now. For each one you’ll see what the opportunity actually is, the problem it solves, who pays, required skills and tools, the business model, how a beginner can start, what a first customer often looks like, realistic challenges, and whether it can grow into full-time work.&lt;br&gt;
If you’re scanning for online work, freelance gigs, or digital business ideas, resources like WorkAtlas can help surface opportunities and communities worth exploring.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;AI Automation Agency (AAA) Services
An AI automation agency designs, builds, and maintains systems that remove repetitive work from businesses. Clients do not buy “AI” in the abstract. They pay for outcomes such as qualified leads entering a CRM automatically, support tickets triaged, invoices processed, appointments booked, reports generated, or internal handoffs that no longer require manual copying between tools.
Common workflows include lead capture and qualification, CRM updates, email sequences, customer support routing, appointment scheduling, reporting dashboards, content pipelines, and internal process automation. Tools often involve n8n, Zapier, Make, Python scripts, APIs, and large language models for classification, extraction, or decision steps.
Business model: Identify a repetitive process → map it → design the automation → build and test → deploy → train the client → maintain and iterate. Revenue typically comes from a setup/project fee plus a monthly retainer for monitoring, updates, and small improvements.
Who can start: Developers, automation specialists, and technically curious people who can learn workflows and basic scripting. Beginners can start by mastering one platform deeply and solving one clear problem for a specific type of business (for example, local service businesses or online coaches).
Beginner roadmap: Pick one vertical. Build 2–3 sample automations. Document the before/after. Offer a fixed-scope pilot at a modest rate. Turn successful pilots into retainers. Specialization (one industry or one workflow type) usually beats generic “AI for any business” positioning.
Challenges: Scoping projects accurately, handling edge cases, tool changes, and selling outcomes rather than tools. Client education takes time. Margins are attractive when delivery is efficient, but poor scoping destroys them.
This can become a full-time agency or a high-value solo practice. Startup capital is low (mainly time and tool accounts).&lt;/li&gt;
&lt;li&gt;AI Content Clipping &amp;amp; Short-Form Video Editing
Long-form content (podcasts, YouTube videos, webinars, interviews, livestreams) contains moments that work as standalone short clips for YouTube Shorts, TikTok, Instagram Reels, and LinkedIn. Clippers find the interesting segments, edit for platform format, add captions and hooks, and prepare publish-ready files.
Workflow: Source long video → AI-assisted transcription and moment detection → human selection and refinement → vertical framing, captions, pacing, text hooks → export and delivery (or posting).
AI tools accelerate transcription, highlight detection, captioning, and basic editing, but judgment about what will hold attention still matters. Creators, podcasters, coaches, course sellers, and brands outsource this because producing volume of quality shorts is time-consuming.
How to start: Create 3–5 strong sample clips from public or permissioned content. Build a simple portfolio. Reach out to creators who already publish long-form, join creator communities, or work through agencies that need volume. Many start with per-clip or per-video pricing and move to retainers.
Realistic view: Beginners often earn modest amounts while learning what performs. Experienced editors with reliable turnaround and platform sense can build steady client work. It is not automatic passive income. Challenges include client feedback loops, platform algorithm changes, and competition from both humans and improving AI tools.
Low capital required. Best suited to people who enjoy editing and understand short-form attention.&lt;/li&gt;
&lt;li&gt;Niche Affiliate Sites Using Programmatic SEO + AI
Affiliate marketing works like this: a visitor finds a useful article or comparison, trusts the recommendation, clicks an affiliate link, and the site earns a commission if a purchase happens. Success depends on buyer-intent keywords, helpful content, and trust.
Modern approaches combine niche focus (a specific audience and problem set), comparison and review content, tutorials, and sometimes programmatic SEO (structured pages generated from data templates). AI assists research, drafting, and variation, but sustainable sites emphasize original testing, expert input, clear search intent matching, editorial quality, and E-E-A-T signals. Publishing large volumes of thin, low-value AI pages is not a durable strategy and risks search penalties.
Monetization: Affiliate commissions (especially recurring SaaS programs), display ads once traffic is meaningful, and occasional sponsorships.
How to start: Choose a narrow niche with commercial intent and available affiliate programs. Validate demand with keyword research. Publish genuinely useful comparison, review, and how-to content. Build topical authority rather than spraying thin pages. Expect months before meaningful traffic and commissions in most cases.
Challenges: Competition, algorithm updates, AI Overview impacts on click-through, and the need for ongoing content quality. Capital needs are low to moderate (domain, hosting, tools, possible paid tools for research).
This can grow into a media-style digital business with recurring revenue, but it rewards patience and quality.&lt;/li&gt;
&lt;li&gt;Remote Sales / Business Development
Remote sales roles include Sales Development Representatives (SDRs/BDRs) who prospect and book meetings, Account Executives who run the full cycle and close, partnership roles, and related lead-generation work. The core activities are research, outreach, qualification, follow-up, and (depending on the role) closing.
Compensation: Often base salary plus commission, or pure commission in some contractor setups. On-target earnings vary widely by role seniority, company stage, deal size, and geography. Entry SDR ranges are typically lower than senior AE packages; top performers in strong markets can earn substantially more through variable pay.
Skills that matter: Clear written and verbal communication, research, resilience with rejection, CRM discipline, structured follow-up, and the ability to understand a product’s value. Technical coding skills are not required.
This path suits people who like talking to others, solving problems through conversation, and working toward measurable targets. Many companies hire fully remote. Challenges include quota pressure, rejection volume, and the need for consistent activity. It can be a strong full-time career or a bridge into higher-responsibility commercial roles.&lt;/li&gt;
&lt;li&gt;Micro-SaaS and Niche Shopify Apps
Micro-SaaS is simple: find a small, painful, recurring problem for a specific group of customers → build focused software that solves it → charge a recurring subscription. Examples include review automation helpers, invoice or reporting tools, AI document processors, scheduling utilities, Shopify store utilities, or internal workflow tools for a narrow vertical.
A small product that deeply solves one job can outperform attempts to build a broad platform. Validation through customer interviews, a minimal viable product, clear pricing, and distribution matter more than feature volume. Recurring revenue is the goal; maintenance, support, and retention become ongoing work.
Simple illustration: 100 customers paying $15 per month equals $1,500 MRR. Reaching and keeping those 100 customers is the hard part.
How to start: Talk to potential users in a specific niche. Identify a workflow they hate. Build the smallest version that delivers value. Price it. Sell it yourself before building more. Shopify App Store distribution is one common channel for e-commerce tools.
Challenges: Finding real demand, distribution, competition from larger tools or platform-native features, and ongoing maintenance. Technical skills help, but no-code/low-code plus AI assistance lowers the barrier for some builders. Capital needs vary; many start lean.
This can become a genuine small business with recurring revenue.&lt;/li&gt;
&lt;li&gt;Online Tutoring &amp;amp; Cohort-Based Courses
People monetize expertise through one-to-one tutoring or structured cohort courses. Subjects range from programming and AI to mathematics, data skills, languages, exam preparation, and professional skills.
One-to-one tutoring offers flexibility and direct feedback. Cohort-based courses create shared timelines, peer interaction, higher completion rates than pure self-paced content, and the ability to serve more students per unit of instructor time. Platforms such as Preply, Wyzant, Maven, and others exist alongside independent teaching via personal sites or community tools.
Validation tip: Test demand with a small paid cohort or limited tutoring slots before building a large course library. Feedback from early students improves the offer.
Challenges: Marketing, scheduling, student retention, and competing on outcomes rather than just content volume. Capital needs are low. Strong subject knowledge plus teaching ability matters more than advanced technical skills. This can scale from side income to a full teaching business or productized course practice.&lt;/li&gt;
&lt;li&gt;Virtual Assistant / Specialized Remote Operations
Generic “answer emails and schedule meetings” VA work exists, but higher-value work comes from specialization: CRM management, AI-assisted research, founder operations support, content operations, customer support systems, e-commerce operations, lead management, or automation-assisted administration.
Progression often looks like: Generic VA → specialized VA in one function or industry → operations specialist → automation-enabled operator who designs processes as well as executes them.
Specialization raises rates and makes the service easier to sell because the buyer immediately understands the outcome. Tools, judgment, and reliability matter. Challenges include client management, scope creep, and the need to keep skills current as AI changes some routine tasks. Capital is essentially zero beyond basic equipment and internet. Suitable for organized, reliable people who like supporting others’ businesses.&lt;/li&gt;
&lt;li&gt;Print-on-Demand + AI-Assisted Designs
The model is straightforward: create a design → list it on a platform → a customer orders → a print partner produces and ships the product → you receive the margin after costs. Inventory risk is minimal because production happens after the order.
Common channels include Etsy, Shopify stores, Amazon Merch, and other POD platforms. AI tools help with brainstorming concepts, generating variations, and creating mockups, but originality, trademark awareness, copyright respect, platform rules, and quality control remain essential. Flooding marketplaces with unedited low-effort AI designs is crowded and increasingly policed.
Realistic view: Success depends on niche selection, design quality that resonates with a specific audience, listing optimization, and marketing. It is not passive income from uploading thousands of generic files. Challenges include competition, platform fee structures, design trends shifting, and policy enforcement around AI and IP. Startup costs are low to moderate. Best for people with design taste or willingness to develop it.&lt;/li&gt;
&lt;li&gt;Freelance AI/ML Engineering &amp;amp; Data Work
Clients hire AI/ML engineers to solve business problems, not to “use AI.” Typical work includes LLM integrations, retrieval-augmented generation (RAG) systems, AI agents, data pipelines, model evaluation, fine-tuning, document processing, computer vision applications, and AI-powered internal tools.
Progression: Build demonstrable skill → create portfolio projects or case studies that show business impact → niche into a problem type or industry → land projects → convert some into ongoing work.
Pricing: Highly variable by experience, specialization (RAG, agents, MLOps, etc.), and client. Senior specialists command premium hourly or project rates; geography and proven results matter. Challenges include staying current, scoping complex projects, and proving reliability in production systems. Strong technical foundation required. Can grow into high-value consulting or productized services.&lt;/li&gt;
&lt;li&gt;Remote Data &amp;amp; Analytics Consulting
Many companies have data scattered across tools but lack clear visibility into what is actually happening in the business. A data consultant turns raw data into organized datasets, reliable metrics, and decision-ready dashboards.
Typical deliverables involve SQL, Python, dbt, tools such as Power BI, Looker, or Tableau, ETL/ELT processes, and KPI reporting. Clients include SaaS companies, e-commerce businesses, agencies, and growing companies that have outgrown spreadsheets.
Business model: Project-based dashboard and pipeline work, plus retainers for ongoing reporting, maintenance, and new analyses. Challenges include messy source data, stakeholder alignment on definitions, and tool sprawl. Skills in data modeling, visualization, and business communication are central. Can start as freelance project work and grow into retained consulting.

Ratings are qualitative and vary by individual skill, niche, and effort.&lt;br&gt;
Which One Should You Choose?&lt;br&gt;
Best for developers: AI automation agencies, Micro-SaaS, freelance AI/ML engineering, and data consulting. These leverage code, systems thinking, and the ability to ship working solutions.&lt;br&gt;
Best for creators: Short-form video clipping, niche affiliate sites, and print-on-demand. These reward content judgment, audience understanding, and creative output.&lt;br&gt;
Best for non-technical beginners: Remote sales, specialized virtual assistant/operations work, and tutoring (if you have teachable knowledge). These emphasize communication, reliability, and domain knowledge over coding.&lt;br&gt;
Best for building a longer-term business: AI automation agencies (retainer model), Micro-SaaS (recurring subscriptions), specialized consulting (retainers), and well-built affiliate media properties. These can compound beyond pure time-for-money tradeoffs.&lt;br&gt;
Choose based on your existing strengths, tolerance for sales, and how much you want to build systems versus deliver services.&lt;br&gt;
How to Start From Zero&lt;/p&gt;

&lt;p&gt;Pick one problem. Start with “I want to solve this specific problem for this specific type of customer,” not “I want to make money online.”&lt;br&gt;
Learn the minimum skills. Acquire just enough to deliver a useful result. Avoid endless preparation.&lt;br&gt;
Build proof. Create a sample project, demo, portfolio piece, case study, or clear before/after example.&lt;br&gt;
Find potential customers. Use direct outreach, communities, job boards, LinkedIn, niche forums, creator networks, and marketplaces. Sites such as WorkAtlas can help surface opportunities and resources.&lt;br&gt;
Sell a specific outcome. “I offer AI services” is weak. “I can automatically capture website leads, qualify them against your criteria, and push qualified prospects into your CRM” is clearer and easier to buy.&lt;br&gt;
Deliver. Focus on solving the stated problem well.&lt;br&gt;
Turn one project into recurring revenue. Add maintenance, monthly reporting, ongoing content production, automation monitoring, software subscriptions, or retainers.&lt;/p&gt;

&lt;p&gt;The Biggest Mistake&lt;br&gt;
Many beginners jump between freelancing, dropshipping, YouTube, SaaS ideas, affiliate marketing, AI agencies, crypto, and e-commerce every few weeks. Focus compounds. Skill, reputation, and distribution take time to build. Pick one path that fits your strengths, learn it deeply enough to deliver results, sell, improve from feedback, and stay with it long enough for the compounding to start.&lt;br&gt;
FAQ&lt;br&gt;
What is the best online hustle in 2026?&lt;/p&gt;

&lt;p&gt;There is no universal best. The strongest fit depends on your skills, preference for technical versus people work, capital, and tolerance for sales versus building. AI-related services and specialized remote work currently show strong demand, but execution matters more than the category label.&lt;br&gt;
Which online hustle requires the least money?&lt;/p&gt;

&lt;p&gt;Specialized virtual assistant work, remote sales (as an employee or contractor), tutoring, and basic content clipping can start with almost no capital beyond a computer and internet connection.&lt;br&gt;
Can I start an AI automation agency without being an AI expert?&lt;/p&gt;

&lt;p&gt;Yes, if you can map processes, use orchestration tools competently, and deliver reliable workflows. Deep research expertise is less necessary than practical integration and client communication skills at the beginning. Specialization helps.&lt;br&gt;
Is Micro-SaaS still worth building?&lt;/p&gt;

&lt;p&gt;Yes for founders who validate a real pain, ship a focused product, and handle distribution. Many small tools still succeed by serving narrow jobs better than generic platforms. Getting paying customers remains the main challenge.&lt;br&gt;
What online hustle is best for developers?&lt;/p&gt;

&lt;p&gt;AI automation, Micro-SaaS, freelance AI/ML work, and data consulting align well with technical strengths and tend to support higher rates or recurring models.&lt;br&gt;
Can AI-generated content still make money?&lt;/p&gt;

&lt;p&gt;It can support processes (research, drafting, variation, clipping assistance), but pure low-effort mass generation of thin pages or designs faces quality and policy headwinds. Human judgment, originality, and usefulness remain differentiators.&lt;br&gt;
How long does it take to get the first online client?&lt;/p&gt;

&lt;p&gt;It varies widely—from a few weeks for skilled freelancers with strong outreach to several months for content sites or products that need traffic or product-market fit. Consistent selling activity shortens the timeline more than perfect preparation.&lt;br&gt;
What is the difference between freelancing and building a digital business?&lt;/p&gt;

&lt;p&gt;Freelancing trades time for money on projects or retainers. A digital business aims for systems, products, or processes that can generate revenue with less linear time input (subscriptions, media properties, productized services, software). Many people start with freelancing and evolve toward more leveraged models.&lt;br&gt;
Final Thoughts&lt;br&gt;
These ten models are real business approaches, not guaranteed income streams. Outcomes depend on the combination of a valuable skill, a genuine customer problem, the ability to reach buyers, and consistent execution over time. Some require technical depth; others reward reliability, communication, or creative taste. Most can begin with limited capital if the focus stays on solving a clear problem.&lt;br&gt;
If you want to keep exploring online work, freelance opportunities, digital business ideas, and communities, WorkAtlas is one practical place to continue looking. Pick one path that fits you, take the first concrete step this week, and improve from real feedback rather than endless planning.&lt;/p&gt;

      <title>Protein Target Verification in Bioactivity Databases: A Practical Workflow from ChEMBL and BindingDB to UniProt</title>
      <dc:creator>Girma</dc:creator>
      <pubDate>Fri, 04 Sep 2026 07:33:46 +0000</pubDate>
      <link>https://dev.to/girma35/protein-target-verification-in-bioactivity-databases-a-practical-workflow-from-chembl-and-4ai0</link>
      <guid>https://dev.to/girma35/protein-target-verification-in-bioactivity-databases-a-practical-workflow-from-chembl-and-4ai0</guid>
      <description>&lt;p&gt;A bioactivity database entry often looks deceptively clean:&lt;br&gt;
Compound → Target name → UniProt ID → Activity value (e.g., IC₅₀ = 12 nM)&lt;br&gt;
At first glance the relationship appears definitive. In reality, the assigned protein target may not match the molecule that was actually studied in the original experiment. Similar protein names, gene-symbol conflicts, species differences, isoforms, orthologs, paralogs, protein-family ambiguity, and incorrect database cross-references all introduce error. When these records later feed machine-learning models or virtual-screening campaigns, the consequences compound: models learn the wrong biology, structure–activity relationships become distorted, and predictions lose reliability.&lt;br&gt;
This article presents a practical, evidence-based workflow for verifying protein-target assignments in ChEMBL and BindingDB against primary literature and UniProt records. The goal is to equip pharmacologists, chemical biologists, bioinformaticians, and AI-driven drug-discovery practitioners with a reproducible method for deciding whether a database annotation is scientifically justified.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Why Protein-Target Assignments Matter
In modern drug discovery, bioactivity data are rarely used in isolation. They are aggregated into training sets for quantitative structure–activity relationship (QSAR) models, chemogenomic matrices, and graph neural networks that link chemical structure to protein targets. An incorrect target assignment is not a minor metadata error; it is a biological false positive or false negative that propagates through every downstream analysis.
Consider a kinase inhibitor annotated against "MAP kinase." Without verification it is impossible to know whether the original assay measured ERK1 (MAPK3), ERK2 (MAPK1), p38α (MAPK14), or a related family member. The UniProt accession, the species, and the precise isoform determine whether the data point belongs in a selectivity model or should be excluded. Systematic verification therefore protects both the integrity of individual records and the statistical validity of large-scale computational work.&lt;/li&gt;
&lt;li&gt;What Is a Protein Target Assignment?
A protein target assignment is a structured claim that a measured biological effect of a small molecule can be attributed to a specific gene product. The logical chain is:
text
Compound
↓
Biological experiment (assay)
↓
Molecular entity actually engaged
↓
Bioactivity measurement (Ki, IC₅₀, Kd, etc.)
↓
Database record
↓
UniProt accession (stable identifier)&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;The database representation is useful only when each arrow is experimentally supported. "Target" in this context means the protein whose function, binding, or activity was directly or indirectly measured, not merely a protein that happens to share a similar name or belongs to the same family.&lt;br&gt;
Key distinctions:&lt;br&gt;
Compound - the chemical entity tested.&lt;br&gt;
Molecular target - the biomolecule whose interaction produces the observed effect.&lt;br&gt;
Protein target - the specific polypeptide (or complex) identified by sequence and function.&lt;br&gt;
Gene - the DNA locus that encodes the protein; gene symbols are often ambiguous across species.&lt;br&gt;
Protein accession - a stable, versioned identifier (most commonly a UniProt accession) that uniquely points to a sequence and its annotation.&lt;br&gt;
Bioactivity measurement - the quantitative or qualitative readout of the experiment.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Understanding ChEMBL and BindingDB
ChEMBL is a large, curated database of bioactive molecules with drug-like properties. It extracts quantitative bioactivity data from the medicinal-chemistry literature and deposits them as structured records linking compounds, assays, targets, and activity values. Each record typically includes:
a literature reference (PubMed or DOI),
an assay description,
a target name and organism,
a preferred UniProt accession (when assigned),
and the measured endpoint (IC₅₀, Ki, EC₅₀, etc.).&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;BindingDB focuses more narrowly on measured binding affinities of protein–ligand complexes. It aggregates data from the literature and from deposited crystal structures, emphasizing thermodynamic and kinetic binding constants. Like ChEMBL, it provides literature links and attempts to map targets to UniProt accessions.&lt;br&gt;
Both resources are indispensable for computational drug discovery because they convert scattered experimental results into machine-readable form. Neither resource is infallible. Curators must interpret complex assay descriptions, resolve nomenclature conflicts, and decide which UniProt entry best represents the experimental system. Ambiguous or incomplete source papers inevitably produce residual uncertainty that only primary-literature verification can resolve.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Understanding UniProt
UniProt is the authoritative repository of protein sequence and functional information. Its core unit is the UniProt Knowledgebase (UniProtKB) entry, identified by a stable accession (e.g., P00533 for human EGFR). Each entry records:
recommended and alternative protein names,
gene names and synonyms,
taxonomic lineage (species),
sequence and isoforms,
functional annotation,
and cross-references to other databases.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;A UniProt accession is far more reliable than a common protein name. "Cyclin-dependent kinase 2" could refer to human CDK2 (P24941), mouse Cdk2 (P97377), or even a related family member if the species or isoform is unspecified. Two proteins may share nearly identical names yet differ in sequence, regulation, or ligand-binding preferences. Mapping every bioactivity record to a precise UniProt accession (including isoform when relevant) removes this ambiguity.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;The Complete Target Verification Workflow
The following stepwise procedure converts a database record into a scientifically defensible assignment:
text
Bioactivity Database Record
      ↓
Identify Reported Target (name, organism, accession)
      ↓
Locate Primary Literature (PubMed / DOI)
      ↓
Read Experimental Evidence (assay description, materials)
      ↓
Identify Protein Actually Studied
      ↓
Determine Species / Source Organism
      ↓
Resolve Gene Symbol, Protein Name, Isoform
      ↓
Compare Against UniProt Entry
      ↓
Confirm, Correct, or Flag the Assignment
      ↓
Document Supporting Evidence&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Step-by-step reasoning&lt;br&gt;
Extract the database claim&lt;br&gt;
Note the target name, organism, UniProt accession (if present), and assay type.&lt;br&gt;
Retrieve the primary paper&lt;br&gt;
Prefer the original experimental report over reviews or secondary citations.&lt;br&gt;
Read the methods and materials&lt;br&gt;
Look for the exact protein used: recombinant construct, purified enzyme, cell line, overexpression system, knockdown, or genetic background. Pay attention to sequence boundaries, tags, mutations, and isoform designations.&lt;br&gt;
Establish species and identity&lt;br&gt;
Confirm whether the protein is human, mouse, rat, or another organism. Orthologs frequently differ in residue numbering and ligand sensitivity.&lt;br&gt;
Resolve nomenclature&lt;br&gt;
Cross-check gene symbols (HUGO for human, MGI for mouse, etc.) against UniProt. Distinguish paralogs (e.g., HDAC1 vs HDAC2) and isoforms produced by alternative splicing.&lt;br&gt;
Map to UniProt&lt;br&gt;
Search UniProt by gene name + organism, then verify that the sequence and functional annotation match the experimental description. Prefer the reviewed (Swiss-Prot) entry when available.&lt;br&gt;
Decide and document&lt;/p&gt;

&lt;p&gt;Confirm the existing accession if evidence aligns.&lt;br&gt;
Correct the accession if a different UniProt entry is clearly indicated.&lt;br&gt;
Flag the record as ambiguous when the paper does not provide sufficient detail.&lt;br&gt;
Record the PubMed ID, the relevant sentence or figure, and the rationale for the final assignment.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;Common Sources of Error and How to Detect&amp;nbsp;Them&lt;br&gt;
Name collision - "Akt" may mean AKT1, AKT2, or AKT3; the paper must specify which isoform was used.&lt;br&gt;
Species mismatch - An assay performed with rabbit enzyme annotated as human UniProt.&lt;br&gt;
Family-level annotation - "Protein kinase C" without specifying the isozyme (α, β, γ, δ, etc.).&lt;br&gt;
Assay target vs. molecular target - A phenotypic screen in cells may list a pathway protein rather than the direct binder.&lt;br&gt;
Isoform or splice-variant omission - Data generated with a truncated or alternatively spliced form mapped to the canonical sequence.&lt;br&gt;
Outdated or withdrawn accessions - UniProt entries are occasionally merged or demerged; always check the current primary accession.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Worked Example (Illustrative)&lt;br&gt;
Suppose ChEMBL reports a compound with IC₅₀ = 8 nM against "Cyclin-dependent kinase 2" and lists UniProt P24941 (human CDK2).&lt;br&gt;
Primary paper describes a biochemical assay using "recombinant human CDK2/cyclin A purified from Sf9 cells."&lt;br&gt;
Sequence and molecular weight match the canonical human CDK2 entry.&lt;br&gt;
No mutations or alternative isoforms are mentioned.&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Conclusion: the assignment to P24941 is supported. If the paper had instead used "mouse Cdk2," the correct accession would be P97377 and the original annotation would require correction.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Implications for Computational and AI-Driven Drug Discovery
Machine-learning models are only as reliable as their training labels. Systematic target verification reduces label noise, improves the quality of chemogenomic datasets, and increases the chance that predicted ligand–target pairs reflect genuine biology. Curated, evidence-linked datasets also enable more meaningful uncertainty estimates and facilitate prospective experimental validation.&lt;/li&gt;
&lt;li&gt;Practical Recommendations
Always prefer primary literature over secondary database summaries.
Treat UniProt accessions as the authoritative identifiers; protein names are secondary.
Record species, isoform, and construct details whenever they are available.
Maintain an audit trail (PubMed ID + rationale) for every verification decision.
When evidence is insufficient, mark the record as "ambiguous" rather than forcing an assignment.
Re-verify critical data points before they enter large-scale modeling pipelines.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Conclusion&lt;br&gt;
Protein-target assignments in bioactivity databases are scientific claims that must be tested against experimental evidence. By systematically tracing each record from ChEMBL or BindingDB through the primary literature to a precise UniProt accession, researchers can convert potentially noisy annotations into high-confidence data. The workflow described here is deliberately conservative: it privileges experimental transparency over completeness. In an era when bioactivity datasets increasingly train predictive models, that conservatism is a scientific necessity rather than an inconvenience.&lt;br&gt;
Accurate target verification is not merely a curation exercise; it is a prerequisite for reliable computational pharmacology and AI-assisted drug discovery.&lt;/p&gt;

      <title>Enterprise Value vs. Equity Value: Understanding the Core Numbers Behind Every M&amp;A Deal</title>

      <description>&lt;p&gt;Imagine a company announces it will buy another for $500 million. Is that $500 million the true value of the business being acquired? In most cases, the answer is more nuanced than it first appears. The $500 million figure could represent the equity value paid to shareholders, the enterprise value of the operating business, or something in between depending on how the deal is structured. Grasping the difference between enterprise value and equity value is one of the most important foundations in M&amp;amp;A valuation.&lt;/p&gt;

&lt;h3&gt;
  
  
  What Equity Value Actually Measures
&lt;/h3&gt;

&lt;p&gt;Equity value is the portion of a company’s total value that belongs to its common shareholders. For public companies, the simplest calculation is market capitalization:&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Equity Value = Current Share Price × Shares Outstanding&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Take a company whose shares trade at $25 with 16 million shares outstanding. Its equity value equals:&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;$25 × 16,000,000 = $400 million&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;This $400 million reflects what the market currently assigns to the residual ownership claim—the claim that sits after debt holders and other creditors have been satisfied. When an acquirer buys 100% of the equity, this is typically the starting point for the consideration paid directly to shareholders.&lt;/p&gt;

&lt;h3&gt;
  
  
  What Enterprise Value Measures
&lt;/h3&gt;

&lt;p&gt;Enterprise value looks at the value of the entire operating business rather than just the equity slice. The standard formula is:&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Enterprise Value = Equity Value + Debt − Cash&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Using the same company:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Equity Value = $400 million
&lt;/li&gt;
&lt;li&gt;Debt = $180 million
&lt;/li&gt;
&lt;li&gt;Cash = $80 million
&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Enterprise Value = $400M + $180M − $80M = $500M&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Debt is added because an acquirer inherits the obligation (or must refinance it). Cash is subtracted because it is a non-operating asset that effectively reduces the net cost of acquiring the business. Enterprise value therefore answers a different question: what is the total value of the operations available to all capital providers?&lt;/p&gt;

&lt;p&gt;If you are exploring how these concepts appear in real corporate development and M&amp;amp;A work, resources such as &lt;a href="https://www.workatlas.tech/" rel="noopener noreferrer"&gt;WorkAtlas&lt;/a&gt; can help surface relevant opportunities and materials.&lt;/p&gt;

&lt;h3&gt;
  
  
  Side-by-Side Comparison
&lt;/h3&gt;

&lt;div class="table-wrapper-paragraph"&gt;&lt;table&gt;
&lt;thead&gt;
&lt;tr&gt;
&lt;th&gt;Concept&lt;/th&gt;
&lt;th&gt;Represents&lt;/th&gt;
&lt;th&gt;Belongs to&lt;/th&gt;
&lt;th&gt;Common Use&lt;/th&gt;
&lt;th&gt;Basic Formula&lt;/th&gt;
&lt;/tr&gt;
&lt;/thead&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td&gt;Equity Value&lt;/td&gt;
&lt;td&gt;Value of the ownership stake&lt;/td&gt;
&lt;td&gt;Common shareholders&lt;/td&gt;
&lt;td&gt;Share price, equity purchase price&lt;/td&gt;
&lt;td&gt;Share price × shares outstanding&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;Enterprise Value&lt;/td&gt;
&lt;td&gt;Value of the operating business&lt;/td&gt;
&lt;td&gt;Equity + debt holders&lt;/td&gt;
&lt;td&gt;Valuation multiples, deal analysis&lt;/td&gt;
&lt;td&gt;Equity Value + Debt − Cash&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;&lt;/div&gt;

&lt;p&gt;The distinction is practical, not academic. Confusing the two leads to incorrect multiples, mispriced offers, and flawed comparisons.&lt;/p&gt;

&lt;h3&gt;
  
  
  Why Enterprise Value Drives M&amp;amp;A Thinking
&lt;/h3&gt;

&lt;p&gt;An acquirer is buying the operating business, not merely a stock certificate. That means the buyer must account for existing debt and any cash that comes with the target. The equity purchase price is what shareholders receive. The economic cost of the transaction is closer to enterprise value, adjusted for deal structure, working-capital true-ups, debt-like items, and transaction expenses.&lt;/p&gt;

&lt;p&gt;Actual cash paid on closing day can differ from the enterprise-value figure depending on whether the deal is structured as a stock purchase, asset purchase, or merger, and whether debt is assumed or refinanced. Enterprise value remains the cleaner metric for comparing businesses and for thinking about the scale of the operating assets being acquired.&lt;/p&gt;

&lt;h3&gt;
  
  
  Linking Enterprise Value to EBITDA
&lt;/h3&gt;

&lt;p&gt;Once enterprise value is established, the most widely used relative valuation metric is EV/EBITDA. EBITDA approximates operating earnings before interest, taxes, and non-cash charges.&lt;/p&gt;

&lt;p&gt;If a company generates $100 million of EBITDA and has an enterprise value of $500 million, the multiple is:&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;EV / EBITDA = $500M / $100M = 5.0x&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;In plain terms, the business is being valued at five times its annual operating earnings before those adjustments. Multiples allow quick size-adjusted comparisons across companies, though they are only as good as the underlying assumptions about growth, margins, and risk.&lt;/p&gt;

&lt;h3&gt;
  
  
  Trading Comparables in Practice
&lt;/h3&gt;

&lt;p&gt;Trading comps start with publicly traded peers:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Identify companies with similar business models, growth rates, and margins.
&lt;/li&gt;
&lt;li&gt;Calculate each peer’s enterprise value.
&lt;/li&gt;
&lt;li&gt;Determine each peer’s EBITDA.
&lt;/li&gt;
&lt;li&gt;Compute the resulting EV/EBITDA multiples.
&lt;/li&gt;
&lt;li&gt;Apply a reasoned multiple (or range) to the target’s EBITDA.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Suppose three relevant peers trade at 4.8×, 5.5×, and 6.1×. An analyst might settle on 5.3× for the target. Applied to $100 million of EBITDA, that implies an enterprise value of $530 million. Subtracting net debt then produces an equity-value estimate. Selecting the right peer set requires judgment; a high-growth software firm should not be forced into the same multiple band as a mature industrial company.&lt;/p&gt;

&lt;h3&gt;
  
  
  Transaction Comparables and Control Premiums
&lt;/h3&gt;

&lt;p&gt;Transaction comps examine what buyers have actually paid in completed deals. These multiples usually incorporate a control premium and often reflect expected synergies. Strategic buyers who can extract cost savings or revenue upside frequently pay higher multiples than pure financial buyers. Market conditions, competitive tension, and the scarcity of quality targets also influence observed premiums. As a result, transaction multiples tend to sit above pure trading multiples.&lt;/p&gt;

&lt;h3&gt;
  
  
  Where DCF Fits
&lt;/h3&gt;

&lt;p&gt;Discounted cash flow valuation estimates enterprise value by projecting future free cash flows and discounting them at the weighted average cost of capital. A terminal value captures the period beyond the explicit forecast. The present value of those cash flows plus the terminal value equals enterprise value; subtracting net debt yields equity value. DCF forces explicit assumptions about growth, reinvestment, and risk. In practice it is used alongside multiples rather than in isolation.&lt;/p&gt;

&lt;h3&gt;
  
  
  From Numbers to a Decision
&lt;/h3&gt;

&lt;p&gt;Valuation alone does not decide a deal. A typical sequence looks like this:&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Strategic rationale → Target valuation → Proposed price → Financing → Synergies → Integration plan → Expected returns → Risk assessment → Go / no-go decision.&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;A target can appear attractive on an EV/EBITDA basis and still be declined if the strategic fit is weak, synergies are speculative, or integration risk is high.&lt;/p&gt;

&lt;h3&gt;
  
  
  A Worked Example
&lt;/h3&gt;

&lt;p&gt;Company A evaluates Company B with the following figures:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Revenue: $350 million
&lt;/li&gt;
&lt;li&gt;EBITDA: $70 million
&lt;/li&gt;
&lt;li&gt;Cash: $30 million
&lt;/li&gt;
&lt;li&gt;Debt: $110 million
&lt;/li&gt;
&lt;li&gt;Shares outstanding: 20 million
&lt;/li&gt;
&lt;li&gt;Share price: $18
&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Current equity value&lt;/strong&gt; = $18 × 20 million = &lt;strong&gt;$360 million&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
&lt;strong&gt;Net debt&lt;/strong&gt; = $110 million − $30 million = &lt;strong&gt;$80 million&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
&lt;strong&gt;Enterprise value&lt;/strong&gt; = $360 million + $80 million = &lt;strong&gt;$440 million&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
&lt;strong&gt;Current EV/EBITDA&lt;/strong&gt; = $440 million / $70 million = &lt;strong&gt;6.3x&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Peer trading multiples range from 6.5× to 7.5×. Company A decides to offer $23 per share, or $460 million for the equity. The implied enterprise value becomes $460 million + $80 million = $540 million, or roughly &lt;strong&gt;7.7x EBITDA&lt;/strong&gt;. Whether that price creates value depends on the synergies Company A can realistically achieve and the cost of financing the transaction.&lt;/p&gt;

&lt;p&gt;People building careers around these analyses often track openings in corporate development and M&amp;amp;A through platforms such as &lt;a href="https://www.workatlas.tech/" rel="noopener noreferrer"&gt;WorkAtlas&lt;/a&gt;.&lt;/p&gt;

&lt;h3&gt;
  
  
  Frequent Pitfalls
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Treating enterprise value and equity value as the same number
&lt;/li&gt;
&lt;li&gt;Forgetting to add debt or subtract cash
&lt;/li&gt;
&lt;li&gt;Mixing EV multiples with equity-value metrics
&lt;/li&gt;
&lt;li&gt;Applying identical multiples to dissimilar companies
&lt;/li&gt;
&lt;li&gt;Assuming a higher multiple is automatically superior
&lt;/li&gt;
&lt;li&gt;Ignoring deal structure, synergies, and financing
&lt;/li&gt;
&lt;li&gt;Treating any single valuation figure as precise rather than an estimate within a range&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Connecting the Concepts to Merger Models
&lt;/h3&gt;

&lt;p&gt;Enterprise value and equity value are only the first layer. A full merger model then incorporates sources and uses of funds, the mix of cash, debt, and stock consideration, shares issued, pro forma financials, accretion or dilution, synergy forecasts, and resulting ownership percentages. These steps turn a valuation range into a concrete view of how the combined company will look and what returns the acquirer can expect.&lt;/p&gt;

&lt;p&gt;Understanding valuation mechanics, comps, DCF, and deal structure is directly relevant for roles in corporate development, M&amp;amp;A, investment banking, and private equity. &lt;a href="https://www.workatlas.tech/" rel="noopener noreferrer"&gt;WorkAtlas&lt;/a&gt; is one place where people exploring those paths can find related openings.&lt;/p&gt;

&lt;h3&gt;
  
  
  Closing Perspective
&lt;/h3&gt;

&lt;p&gt;Equity value measures what belongs to shareholders. Enterprise value measures the operating business relative to all capital providers. That single distinction underpins trading comps, transaction comps, DCF work, acquisition pricing, merger models, and accretion/dilution analysis.&lt;/p&gt;

&lt;p&gt;The most useful habit when learning M&amp;amp;A valuation is not memorizing formulas but understanding what each number represents and why the calculation is performed. Once the intuition is solid, the rest of the analytical toolkit becomes far easier to apply. For those continuing to deepen their knowledge of corporate development and M&amp;amp;A, &lt;a href="https://www.workatlas.tech/" rel="noopener noreferrer"&gt;WorkAtlas&lt;/a&gt; offers a practical way to stay connected to relevant opportunities in the field.&lt;/p&gt;

      <description>&lt;h1&gt;
  
  
  10 Future-Proof Skills That Will Still Pay Extremely Well in 2027 (Even When AI Is Everywhere)
&lt;/h1&gt;

&lt;p&gt;AI is getting smarter every month. Many people are worried that machines will take most jobs. But the truth is different.&lt;/p&gt;

&lt;p&gt;In 2027, the highest earners will not be the people who compete with AI. They will be the ones who use AI as a tool while mastering skills that still need strong human judgment, creativity, and technical depth.&lt;/p&gt;

&lt;p&gt;Here are 10 high-income skills that AI is unlikely to replace soon — and exactly where you can find real paying opportunities for them.&lt;/p&gt;

&lt;h3&gt;
  
  
  1. AI Agents &amp;amp; Workflow Automation Architecture
&lt;/h3&gt;

&lt;p&gt;Writing simple ChatGPT prompts is no longer a skill. Companies now pay people who can design complete multi-agent systems that connect AI to real business tools, databases, and workflows.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Core tools:&lt;/strong&gt; Python, LangChain, AutoGen, Flowise, custom APIs, vector databases  &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Average earning potential:&lt;/strong&gt; $90–$180 per hour  &lt;/p&gt;

&lt;p&gt;You can browse ranked, community-reviewed platforms that include authentic payout evidence directly on &lt;a href="https://www.workatlas.tech/" rel="noopener noreferrer"&gt;https://www.workatlas.tech/&lt;/a&gt;.&lt;/p&gt;

&lt;h3&gt;
  
  
  2. Full-Stack RAG &amp;amp; Vector Database Engineering
&lt;/h3&gt;

&lt;p&gt;Businesses want AI that answers questions using their private data — without leaking information. Engineers who build secure Retrieval-Augmented Generation systems are in very high demand.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Core tools:&lt;/strong&gt; Next.js, NestJS, PostgreSQL + pgvector, Redis, Docker  &lt;/p&gt;

&lt;h3&gt;
  
  
  5. Fractional AI Data Annotation &amp;amp; Model Evaluation
&lt;/h3&gt;

&lt;p&gt;Even the best AI models need high-quality human feedback. People with domain knowledge (especially in tech, math, or science) are paid well to evaluate and improve these systems.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Core tools:&lt;/strong&gt; Python, RLHF frameworks, evaluation protocols  &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Average earning potential:&lt;/strong&gt; $25–$65 per hour  &lt;/p&gt;

&lt;p&gt;You can browse ranked, community-reviewed platforms that include authentic payout evidence directly on &lt;a href="https://www.workatlas.tech/" rel="noopener noreferrer"&gt;https://www.workatlas.tech/&lt;/a&gt;.&lt;/p&gt;

&lt;h3&gt;
  
  
  6. Full-Stack Web &amp;amp; Mobile App Development
&lt;/h3&gt;

&lt;p&gt;Building fast, clean, and reliable applications is still a highly paid skill — especially when combined with modern stacks that load quickly and scale well.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Core tools:&lt;/strong&gt; Next.js, React, TypeScript, Flutter, Tailwind, Node.js  &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Average earning potential:&lt;/strong&gt; $70–$140 per hour  &lt;/p&gt;

&lt;p&gt;You can browse ranked, community-reviewed platforms that include authentic payout evidence directly on &lt;a href="https://www.workatlas.tech/" rel="noopener noreferrer"&gt;https://www.workatlas.tech/&lt;/a&gt;.&lt;/p&gt;

&lt;h3&gt;
  
  
  7. Conversion Rate Optimization (CRO) &amp;amp; UI/UX Audits
&lt;/h3&gt;

&lt;p&gt;Traffic is expensive. Companies desperately need people who can turn visitors into customers through better design, testing, and user psychology.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Core tools:&lt;/strong&gt; Figma, Hotjar, Google Analytics, A/B testing tools  &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Average earning potential:&lt;/strong&gt; $1,500–$5,000 per project  &lt;/p&gt;

&lt;h3&gt;
  
  
  8. Cloud-Native Infrastructure &amp;amp; DevOps Automation
&lt;/h3&gt;

&lt;p&gt;Someone still has to make sure applications stay online, secure, and cost-efficient. Skilled DevOps engineers remain essential.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Core tools:&lt;/strong&gt; Docker, Linux, Nginx, CI/CD, DigitalOcean  &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Average earning potential:&lt;/strong&gt; $75–$130 per hour  &lt;/p&gt;

&lt;h3&gt;
  
  
  9. Automated Social Messaging &amp;amp; Localized Chatbot Engineering
&lt;/h3&gt;

&lt;p&gt;Businesses want automated customer support on WhatsApp and Telegram that actually understands local languages and context. Building these systems pays well.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Core tools:&lt;/strong&gt; Telegram Bot API, WhatsApp Business API, Node.js/Python  &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Average earning potential:&lt;/strong&gt; $1,000–$3,500 per project  &lt;/p&gt;

&lt;h3&gt;
  
  
  10. Quantitative Data Analysis &amp;amp; Predictive Modeling
&lt;/h3&gt;

&lt;p&gt;AI can process data, but interpreting messy real-world information and building useful prediction models still requires human expertise.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Core tools:&lt;/strong&gt; Python, Pandas, Scikit-learn, LightGBM, Jupyter  &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Average earning potential:&lt;/strong&gt; $65–$125 per hour  &lt;/p&gt;

&lt;h3&gt;
  
  
  Final Advice
&lt;/h3&gt;

&lt;p&gt;Don’t try to learn all ten skills. Pick the one that matches your current background or interest. Build a few real projects. Then go find actual paying work.&lt;/p&gt;

&lt;p&gt;The people who will earn the most in 2027 are not waiting for AI to “settle down.” They are already building skills that AI cannot easily replace — and placing those skills where the money already is.&lt;/p&gt;

&lt;p&gt;Start today. One skill. Real projects. Then use &lt;a href="https://www.workatlas.tech/" rel="noopener noreferrer"&gt;https://www.workatlas.tech/&lt;/a&gt; to turn that skill into income.&lt;/p&gt;

      <guid>https://dev.to/girma35/how-i-automated-sales-call-list-generation-with-claude-ai-apify-and-mcp-116p</guid>
      <description>&lt;p&gt;If you've ever built a sales call list by hand, you know the drill. Open Google Maps. Search "roofing companies near me." Click into each listing. Open the website in a new tab. Hunt for a phone number that isn't hidden behind a "Contact Us" form. Copy it into a spreadsheet. Repeat two hundred times. By the time you're done, you've spent an entire day doing work that generates zero revenue and mostly just makes your eyes hurt.&lt;br&gt;
I hit this wall a few months ago while helping a small B2B services team build out their outbound pipeline. They needed a call list of 300+ local businesses in a specific niche, with verified phone numbers and emails, ranked by how "callable" they actually were. Manual research was going to eat a week of someone's time - and even then, the data quality would be inconsistent because humans get tired and start copy-pasting sloppily around hour four.&lt;br&gt;
So I built an automated pipeline instead. It combines three things that, individually, are each pretty useful, but together turn into something genuinely powerful:&lt;br&gt;
Apify for web scraping and business discovery at scale&lt;br&gt;
The Model Context Protocol (MCP) to give an AI model direct, structured access to that data&lt;br&gt;
Claude AI to qualify, rank, and clean the leads into something a sales rep can actually work from&lt;/p&gt;

&lt;p&gt;In this post, I'll walk through the entire workflow end to end - how it discovers businesses, extracts contact details, hands that data to Claude, and spits out a prioritized sales call list. I'll also share the architecture, some example output, and honest thoughts on where this approach shines and where it still needs a human in the loop.&lt;br&gt;
The Core Problem With Manual Lead Generation&lt;br&gt;
Before getting into the solution, it's worth being explicit about why manual lead list building is such a bad use of time:&lt;br&gt;
It doesn't scale. Finding 20 leads by hand is fine. Finding 500 is a part-time job.&lt;br&gt;
Data quality is inconsistent. Different people copy data differently - some grab a fax number by mistake, some skip the direct line and grab a generic support number instead.&lt;br&gt;
There's no qualification layer. A raw list of business names and phone numbers isn't a sales call list - it's just contacts. You still need to figure out which ones are worth calling first.&lt;br&gt;
It's demoralizing. Nobody wants to spend their day copy-pasting from browser tabs into a spreadsheet.&lt;/p&gt;

&lt;p&gt;Automating discovery and extraction solves the scale and consistency problems. Adding an AI qualification layer solves the "which leads matter" problem. That's the whole pitch.&lt;br&gt;
Meet the Actor: Sales Call List Generator&lt;br&gt;
The engine behind the discovery and extraction stage of this workflow is an Apify actor called the Sales Call List Generator. Its job, in plain terms, is to automatically discover businesses, extract contact information, and generate high-quality sales call lists from websites using AI-powered data extraction. You give it a keyword or niche, and it goes out, finds relevant businesses, crawls their websites, and comes back with structured contact data instead of a pile of raw HTML.&lt;br&gt;
Concretely, the actor can:&lt;br&gt;
Discover businesses matching a search term or industry niche&lt;br&gt;
Crawl company websites to find relevant pages automatically&lt;br&gt;
Find phone numbers, even when they're buried in a footer or a contact page rather than the homepage&lt;br&gt;
Extract email addresses from contact forms, footers, and "about us" pages&lt;br&gt;
Locate contact pages so you have a direct link if a phone number isn't listed&lt;br&gt;
Collect company names in a normalized format&lt;br&gt;
Gather website URLs for every business found&lt;br&gt;
Extract physical addresses when available&lt;br&gt;
Find social media profiles - LinkedIn, Facebook, Instagram, X - when a business has them linked&lt;br&gt;
Produce structured sales lead data in a clean, machine-readable format (typically JSON, which is what makes the next stage of this pipeline possible)&lt;/p&gt;

&lt;p&gt;The part that makes this genuinely different from a basic scraper is that AI is doing real work under the hood to clean, organize, and structure the collected information. Instead of you writing regex to guess which ten-digit number on a page is actually the business's main line, the AI layer inside the actor makes that judgment call, and instead of a wall of scraped text, you get tidy fields: business name, phone, email, address, and so on.&lt;br&gt;
If you want to see it in action or plug it into your own workflow, the actor is public on Apify here: Sales Call List Generator. It's worth exploring the actor's input schema directly - you can tune things like the search niche, geographic scope, and how deep it crawls each site.&lt;br&gt;
The Complete Automation Pipeline&lt;br&gt;
Here's the full pipeline, from a cold keyword to a ranked call list sitting in front of a sales rep.&lt;br&gt;
Step 1 - Discover Businesses&lt;br&gt;
Everything starts with a search input. You tell the actor what kind of business you're targeting - this could be an industry ("roofing companies," "dentists," "restaurants," "SaaS companies," "real estate agencies") or something more specific like "boutique law firms in Austin." The actor takes that input and searches for matching businesses, then queues up their websites for crawling.&lt;br&gt;
This is the step that used to take the most manual time. Instead of scrolling through search results and maps listings one at a time, the actor batches this discovery process and hands off a list of business websites to crawl. From there, it visits each site and starts pulling out the contact information that actually matters for a sales call.&lt;br&gt;
Important Note&amp;nbsp;: use this actor is public on Apify here: Sales Call List Generator. It's worth exploring the actor's input schema directly - you can tune things like the search niche, geographic scope, and how deep it crawls each site.&lt;br&gt;
Step 2 - Extract Contact Information&lt;br&gt;
For every business discovered, the actor extracts a consistent set of fields:&lt;br&gt;
Business Name&lt;br&gt;
Website&lt;br&gt;
Phone Number&lt;br&gt;
Email Address&lt;br&gt;
Contact Page (a direct link, useful as a fallback when no phone/email is found)&lt;br&gt;
Physical Address&lt;br&gt;
Industry&lt;br&gt;
Social Profiles&lt;/p&gt;

&lt;p&gt;Why does this matter so much? Because the difference between "a list of company names" and "a sales call list" is exactly this extraction step. A rep can't call a company name. They need a phone number, ideally an email as a backup channel, and enough context (industry, address) to open the call with something relevant to say. Automated extraction does this at a speed no human researcher can match - we're talking hundreds of businesses processed while you'd still be finishing your coffee, versus the hours or days it would take to do the same research by hand, one browser tab at a time.&lt;br&gt;
Step 3 - Connect Apify to Claude AI Using&amp;nbsp;MCP&lt;br&gt;
This is where the pipeline goes from "scraper" to "AI-powered workflow," and it's worth slowing down to explain the moving part that makes it work: the Model Context Protocol, or MCP.&lt;br&gt;
In simple terms, MCP is a standard that lets AI models like Claude connect directly to external tools and data sources - APIs, databases, files, or in this case, structured data produced by Apify - without you having to manually copy-paste that data into a chat window or write custom glue code for every integration. Think of it like a universal adapter: instead of Claude only being able to "see" what you type or paste, MCP gives it a defined way to request and receive structured data from a connected source, the same way a plug fits a specific socket regardless of what appliance is on the other end.&lt;br&gt;
In this pipeline, once the Apify actor finishes running and produces its structured dataset (a clean JSON list of businesses with names, phones, emails, addresses, and so on), that dataset is exposed to Claude through an MCP connection. That means Claude isn't just seeing a summary or a small snippet - it can work with the full dataset as structured data, which unlocks a few things:&lt;br&gt;
Read thousands of leads in one working context rather than being limited to whatever fits in a single copy-pasted message&lt;br&gt;
Understand the structured format natively - it knows this row is a phone number, this one's an email, this one's an address, rather than treating everything as an undifferentiated blob of text&lt;br&gt;
Filter bad contacts - malformed phone numbers, obviously fake emails, empty fields&lt;br&gt;
Detect missing information and flag which leads need manual follow-up&lt;br&gt;
Rank businesses based on how complete and "callable" their data is&lt;br&gt;
Generate summaries of the dataset as a whole (e.g., "72% of leads have both phone and email; restaurants had the highest data completeness")&lt;br&gt;
Recommend outreach priorities - which leads to call first, and why&lt;/p&gt;

&lt;p&gt;The practical setup usually looks like this: the Apify actor run produces a dataset, an MCP server exposes that dataset (or the Apify API) as a callable resource, and Claude connects to that MCP server as a client. From there, you can literally ask Claude things like "rank these leads by call priority and tell me which ones are missing phone numbers" and get back an answer grounded in the actual dataset, not a hallucinated guess.&lt;br&gt;
Step 4 - AI Lead Qualification&lt;br&gt;
Raw contact data isn't the same thing as a qualified lead. This is the step most automated scraping tools skip entirely, and it's the one that actually saves a sales team the most time.&lt;br&gt;
Once Claude has access to the dataset via MCP, it evaluates each business against a few practical signals:&lt;br&gt;
Which companies appear active - do they have a working website, recent content, a functioning contact page?&lt;br&gt;
Which companies have valid contact information - properly formatted phone numbers and emails, not placeholder text or broken links&lt;br&gt;
Which businesses are worth calling - based on completeness of data and relevance to the target niche&lt;br&gt;
Which businesses should be skipped - dead websites, missing all contact info, obvious duplicates&lt;br&gt;
Which leads should receive the highest priority - typically those with both a direct phone number and email, a real physical address, and clear signs of an active business&lt;/p&gt;

&lt;p&gt;This qualification pass is what turns "500 scraped businesses" into "80 leads worth a sales rep's time this week." Doing this manually would mean someone opening every single website again just to sanity-check it - which defeats the entire purpose of automating the first two steps. Having Claude do this reasoning over the structured dataset means the qualification logic scales exactly as well as the scraping does.&lt;br&gt;
Step 5 - Generate the Final Sales Call&amp;nbsp;List&lt;br&gt;
The last step is producing the actual deliverable: a clean, ranked table a sales rep can open and start working immediately. Here's an example of what that output looks like in practice, using realistic sample data for a "dentists" niche search:&lt;br&gt;
Business Website Phone Email Priority Notes Bright Smile Dental Clinic brightsmiledental.com (512) 555–0142 &lt;a href="mailto:info@brightsmiledental.com"&gt;info@brightsmiledental.com&lt;/a&gt; High Full contact info, active blog, recent reviews Riverside Family Dentistry riversidefamilydds.com (512) 555–0198 &lt;a href="mailto:contact@riversidefamilydds.com"&gt;contact@riversidefamilydds.com&lt;/a&gt; High Complete profile, LinkedIn active Oakview Orthodontics oakvieworthocenter.com (512) 555–0110 - Medium No email found, has contact form Downtown Dental Group downtowndentalgrp.com - &lt;a href="mailto:hello@downtowndentalgrp.com"&gt;hello@downtowndentalgrp.com&lt;/a&gt; Medium Phone missing, email verified Sunrise Dental Studio sunrisedentalstudio.com (512) 555–0176 &lt;a href="mailto:appointments@sunrisedentalstudio.com"&gt;appointments@sunrisedentalstudio.com&lt;/a&gt; High Active social profiles, address confirmed Legacy Dental Partners legacydentalpartners.com - - Low Website appears outdated, no working contact info&lt;br&gt;
Notice how the "Priority" and "Notes" columns aren't things the raw scraper produced - they're Claude's qualification layer at work, reasoning over completeness and business activity to tell a rep exactly where to start. That's the difference between a scraped dataset and an actual sales call list.&lt;br&gt;
Architecture Diagram&lt;br&gt;
Here's the full pipeline laid out visually, from initial search input to the final list landing in a rep's hands:&lt;br&gt;
flowchart LR&lt;br&gt;
A[Search Businesses]&lt;br&gt;
--&amp;gt; B[Apify Sales Call List Generator]&lt;br&gt;
--&amp;gt; C[Extract Contact Information]&lt;br&gt;
--&amp;gt; D[MCP Server]&lt;br&gt;
--&amp;gt; E[Claude AI]&lt;br&gt;
--&amp;gt; F[Lead Qualification]&lt;br&gt;
--&amp;gt; G[Final Sales Call List]&lt;br&gt;
Each box maps directly to a step above: the search kicks off the actor, the actor discovers and extracts, the structured output is exposed over MCP, Claude reads it, qualifies it, and the result is a call list ready for outreach.&lt;br&gt;
Why This Combination Works Better Than Either Tool&amp;nbsp;Alone&lt;br&gt;
It's worth being clear-eyed about why you need both halves of this pipeline, rather than just one or the other.&lt;br&gt;
Apify alone gets you fast, scalable data collection. You can run the Sales Call List Generator actor against any niche and get a structured dataset of businesses back in minutes instead of days. But a scraper, on its own, doesn't know which leads are actually good. It'll happily hand you a business with a dead website right next to one that's clearly thriving, with no distinction between them.&lt;br&gt;
Claude alone, without MCP, would have no way to reliably work with a live, large, structured dataset - you'd be stuck manually pasting chunks of data into a chat window, which breaks down fast once you're past a few dozen rows and loses the benefit of having structured fields in the first place.&lt;br&gt;
Together, via MCP, you get scale from Apify and judgment from Claude, connected without manual data wrangling in between. That combination is really the point of MCP in general: it's not just about connecting AI to any data - it's about connecting AI to structured, live data in a way that preserves the structure, so the model can reason over fields instead of guessing at unstructured text.&lt;br&gt;
Practical Tips If You're Building This&amp;nbsp;Yourself&lt;br&gt;
A few things I learned putting this together that are worth passing on:&lt;br&gt;
Be specific with your niche input. "Dentists" returns a broad, noisy set. "Cosmetic dentists in Austin, TX" returns a tighter, more relevant one. The narrower your search, the less qualification work Claude has to do downstream.&lt;br&gt;
Don't skip the qualification step. It's tempting to just export the raw Apify dataset straight into your CRM. Resist that - an unqualified list buries your best leads next to your worst ones, and your reps will burn goodwill calling dead numbers.&lt;br&gt;
Treat "Low" priority as a queue, not trash. Some low-priority leads just have incomplete data, not zero potential. A quick manual check on those can still turn up real opportunities.&lt;br&gt;
Re-run periodically. Business contact info changes. A call list from six months ago is stale - treat this as a pipeline you re-run on a schedule (weekly or monthly, depending on your outbound volume), not a one-time export.&lt;br&gt;
Keep a human in the loop for edge cases. AI qualification is good at spotting patterns (missing fields, dead sites) but it's not infallible. Spot-check a sample of the "High" priority leads before your team starts dialing.&lt;/p&gt;

&lt;p&gt;Wrapping Up&lt;br&gt;
What used to be a multi-day manual research project - searching for businesses, opening dozens of tabs, copy-pasting contact details, and then trying to guess which leads were worth prioritizing - now runs as a repeatable pipeline: Apify discovers and extracts, MCP connects that structured data to Claude, and Claude qualifies and ranks it into a call list a sales rep can start working the same day.&lt;br&gt;
If you're a developer or founder looking to build something similar, the fastest way to get a feel for it is to try the actor directly and see the shape of the data it produces before you build the MCP and qualification layers on top. You can find it on Apify here: Sales Call List Generator.&lt;br&gt;
The bigger takeaway, honestly, isn't really about sales call lists specifically - it's about the pattern. Scraper for scale, MCP for the connective tissue, LLM for judgment. That pattern generalizes to a lot of workflows beyond lead generation, and it's a genuinely useful template to have in your back pocket the next time you're staring down a pile of repetitive manual research.&lt;/p&gt;

      <title>What to Learn as a Developer in the AI Era — Part 2</title>
      <dc:creator>Girma</dc:creator>
      <pubDate>Tue, 26 May 2026 20:22:21 +0000</pubDate>
      <link>https://dev.to/girma35/what-to-learn-as-a-developer-in-the-ai-era-part-2-da4</link>
      <guid>https://dev.to/girma35/what-to-learn-as-a-developer-in-the-ai-era-part-2-da4</guid>
      <description>&lt;p&gt;In Part 1, we covered the highest-priority skills every developer needs in the AI era  system design, debugging, prompt engineering, code review, and testing. Now let's look at what still matters, what's new, and how to put it all together into a concrete learning plan.&lt;/p&gt;




&lt;h2&gt;
  
  
  🟡 Medium priority — still important, but AI helps a lot
&lt;/h2&gt;

&lt;p&gt;These skills haven't gone away. AI assists with them heavily, but you still need a solid foundation to catch mistakes and make good decisions.&lt;/p&gt;

&lt;h3&gt;
  
  
  Git &amp;amp; version control
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;You still manage codebases and collaborate with teams&lt;/li&gt;
&lt;li&gt;Reviewing AI-generated commits and diffs is a daily task&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  SQL &amp;amp; databases
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;AI writes queries, but you design the schemas&lt;/li&gt;
&lt;li&gt;Understanding indexes, relations, and performance still matters&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Core algorithms &amp;amp; data structures
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Needed to evaluate whether an AI solution is actually good&lt;/li&gt;
&lt;li&gt;Interviews still test these — they're not going away&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  One backend language — deeply
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Python, Node.js, or Go — pick one and go deep&lt;/li&gt;
&lt;li&gt;Surface-level knowledge won't help you fix AI mistakes&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  One frontend framework
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;React is still dominant; knowing it well opens most doors&lt;/li&gt;
&lt;li&gt;AI generates components fast — you need to review and improve them&lt;/li&gt;
&lt;/ul&gt;




&lt;h2&gt;
  
  
  🟢 New skills to add
&lt;/h2&gt;

&lt;p&gt;These are the skills that barely existed five years ago but are now essential.&lt;/p&gt;

&lt;h3&gt;
  
  
  AI tools fluency
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Learn Claude Code, Cursor, and GitHub Copilot deeply — not just casually&lt;/li&gt;
&lt;li&gt;Know how to use AI agents, not just chat interfaces&lt;/li&gt;
&lt;li&gt;The developer who masters these tools ships 5–10x faster&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Working with APIs &amp;amp; integrations
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Modern software is largely about connecting services together&lt;/li&gt;
&lt;li&gt;REST, webhooks, OAuth, JWT, and third-party APIs are daily work&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  DevOps basics
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Docker, CI/CD pipelines, and basic cloud (AWS, GCP, or Vercel)&lt;/li&gt;
&lt;li&gt;Deploying and monitoring your own software is now a baseline skill&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Product thinking
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Developers who understand &lt;em&gt;why&lt;/em&gt; they are building something make far better decisions&lt;/li&gt;
&lt;li&gt;Talk to users, understand the problem before writing a single line&lt;/li&gt;
&lt;/ul&gt;




&lt;h2&gt;
  
  
  The mental shift
&lt;/h2&gt;

&lt;div class="table-wrapper-paragraph"&gt;&lt;table&gt;
&lt;thead&gt;
&lt;tr&gt;
&lt;th&gt;Old era&lt;/th&gt;
&lt;th&gt;AI era&lt;/th&gt;
&lt;/tr&gt;
&lt;/thead&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td&gt;Write every line yourself&lt;/td&gt;
&lt;td&gt;Direct AI, review output&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;Memorize syntax&lt;/td&gt;
&lt;td&gt;Know concepts deeply&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;Specialist in one stack&lt;/td&gt;
&lt;td&gt;Generalist who moves fast&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;Months to build features&lt;/td&gt;
&lt;td&gt;Days to ship with AI&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;Junior dev = code writer&lt;/td&gt;
&lt;td&gt;Junior dev = AI wrangler + reviewer&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;&lt;/div&gt;




&lt;h2&gt;
  
  
  12-month learning path
&lt;/h2&gt;



&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight plaintext"&gt;&lt;code&gt;Month 1–2:   Pick one language deeply (Python or JavaScript)
Month 3–4:   System design basics + databases
Month 5–6:   Build a real project using Claude Code or Cursor
Month 7–8:   DevOps — Docker, deployment, CI/CD
Month 9–10:  APIs, integrations, authentication
Month 11–12: Contribute to or build something real people use
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;






&lt;h2&gt;
  
  
  The one-sentence summary
&lt;/h2&gt;

&lt;blockquote&gt;
&lt;p&gt;Learn to think like an architect, communicate like a tech lead, and use AI like a power tool — the developers who do this will be 10x more productive than those who don't.&lt;/p&gt;
&lt;/blockquote&gt;

      <title>What to Learn as a Developer in the AI Era — Part 1</title>
      <dc:creator>Girma</dc:creator>
      <pubDate>Tue, 26 May 2026 20:07:51 +0000</pubDate>
      <link>https://dev.to/girma35/what-to-learn-as-a-developer-in-the-ai-era-part-1-5c8i</link>
      <guid>https://dev.to/girma35/what-to-learn-as-a-developer-in-the-ai-era-part-1-5c8i</guid>
      <description>&lt;p&gt;AI is rewriting how software gets built. But it doesn't replace the developer — it changes which skills matter most. Here's what you should double down on, and what's shifting in priority.&lt;/p&gt;




&lt;h2&gt;
  
  
  1. Don't stop learning to code
&lt;/h2&gt;

&lt;p&gt;AI writes code, but it makes mistakes, hallucinates APIs, and can't debug complex systems alone. You need to read, review, and fix AI-generated code — and that requires genuine coding knowledge. The developer who understands the code will always outperform the one who just copies what the AI produces.&lt;/p&gt;




&lt;h2&gt;
  
  
  The new priority stack
&lt;/h2&gt;

&lt;p&gt;🔴 &lt;strong&gt;Highest priority — now more valuable than ever&lt;/strong&gt;&lt;/p&gt;

&lt;h3&gt;
  
  
  System design &amp;amp; architecture
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;How to break large systems into modules&lt;/li&gt;
&lt;li&gt;API design, database modeling, microservices vs monolith&lt;/li&gt;
&lt;li&gt;AI can't design systems — this is purely human work&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Problem solving &amp;amp; debugging
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;When AI-generated code breaks, you have to fix it&lt;/li&gt;
&lt;li&gt;Understanding why something fails is irreplaceable&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Prompt engineering for code
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Writing precise, context-rich prompts&lt;/li&gt;
&lt;li&gt;Knowing how to give AI the right constraints&lt;/li&gt;
&lt;li&gt;This is now a core developer skill&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Reading &amp;amp; reviewing code
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;You'll read more AI code than you write&lt;/li&gt;
&lt;li&gt;Code review becomes your most important daily skill&lt;/li&gt;
&lt;/ul&gt;

&lt;h3&gt;
  
  
  Testing &amp;amp; quality thinking
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;Always ask: "How do I know this works?"&lt;/li&gt;
&lt;li&gt;Writing tests, defining edge cases, thinking about failure&lt;/li&gt;
&lt;/ul&gt;




&lt;p&gt;&lt;em&gt;Continue to **Part 2&lt;/em&gt;* — where we cover medium-priority skills, what's new to add, and a full 12-month learning path.&lt;/p&gt;

      <description>&lt;p&gt;Hey folks,&lt;br&gt;
If you're anything like me, you're constantly spotting problems that AI could solve in a smarter, faster way. The best SaaS products don't just use AI for the sake of it they fix real headaches and make people willing to pay because the value is obvious.&lt;br&gt;
Here are five ideas I'm genuinely excited about right now in April 2026. Each one is simple to explain, solves a daily pain point, and has clear customers who would happily open their wallets. Let's dive in.&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;AI Resume Tailoring SaaS
Upload a job post + your resume → the AI rewrites everything to match that exact role and makes it ATS-friendly in seconds.
No more spending hours tweaking bullet points or guessing what keywords the recruiter's system is scanning for. Job seekers get interviews faster, recruiters spend less time sifting through junk applications, and career coaches can offer it as a premium service.
Why people will pay: Getting your foot in the door for the right job is worth way more than the monthly subscription.
Ready to turn this idea into a real product? Build, launch, and grow your SaaS with a partner who actually cares → &lt;a href="https://www.girma.studio/" rel="noopener noreferrer"&gt;https://www.girma.studio/&lt;/a&gt;
&lt;/li&gt;
&lt;li&gt;Meeting Prep Assistant for Sales&amp;nbsp;Teams
Connect your calendar, CRM, and LinkedIn. Thirty minutes before every call, you get a crisp one-page brief: who you're talking to, recent company news, past interactions, mutual connections, and the three smartest questions to ask.
Sales reps close more deals, agencies look sharper in client meetings, and busy founders stop scrambling.
Why people will pay: Prep time drops from 45 minutes to 5, and win rates go up. That's money in the bank.
Don't just dream about it - ship it. We build your SaaS, deploy it live, and stick around for ongoing support → &lt;a href="https://www.girma.studio/" rel="noopener noreferrer"&gt;https://www.girma.studio/&lt;/a&gt;
&lt;/li&gt;
&lt;li&gt;AI Email Briefing for Busy&amp;nbsp;Founders
Every morning you open one clean dashboard that scans your inbox and tells you: urgent replies needed today, hot leads that just wrote back, follow-ups you promised, and everything else you can safely ignore until tomorrow.
Founders, executives, and freelancers get hours of their life back every single week.
Why people will pay: Your inbox stops owning your day. You stay on top of what matters without drowning in it.
Stop imagining and start building. Turn your SaaS idea into a launched business with full development + deployment + follow-up support → &lt;a href="https://www.girma.studio/" rel="noopener noreferrer"&gt;https://www.girma.studio/&lt;/a&gt;
&lt;/li&gt;
&lt;li&gt;Telegram AI Customer Support&amp;nbsp;Bot
Businesses get their own smart Telegram bot that instantly answers FAQs, books appointments, qualifies leads, and even collects payments all inside the app their customers already use every day.
Local businesses, coaches, and ecommerce sellers finally have 24/7 support without hiring extra staff.
Why people will pay: It feels like having a full-time customer support person who never sleeps and costs a fraction of the price.
Your idea deserves to exist. We build it, ship it, and keep it running smoothly for you → &lt;a href="https://www.girma.studio/" rel="noopener noreferrer"&gt;https://www.girma.studio/&lt;/a&gt;
&lt;/li&gt;
&lt;li&gt;Website Security Scanner for&amp;nbsp;SMBs
One-click scan of any website or web app that flags vulnerabilities, SSL problems, exposed API keys, outdated plugins, and security gaps then gives you a plain-English report with exact fixes.
Small companies, agencies, and early-stage SaaS startups can finally stay safe without needing a full-time security expert.
Why people will pay: One hack can kill trust and revenue. Preventing it is cheap insurance.
Time to stop dreaming and start shipping. Partner with us at &lt;a href="https://www.girma.studio/" rel="noopener noreferrer"&gt;https://www.girma.studio/&lt;/a&gt; we build your SaaS, deploy the app, and provide ongoing support so you can focus on growth.
Which one of these fired you up the most? Or do you have your own twist on an AI SaaS idea? Drop it in the comments I read every single one.
And if you're serious about turning any of these (or your own idea) into a real, revenue-generating product instead of another forgotten note in Notion… you know where to go.
See you on the other side of "launched.&lt;/li&gt;
&lt;/ol&gt;

      <title>Starting Point for Kagglers: Customer Churn Prediction Competition</title>
      <dc:creator>Girma</dc:creator>
      <pubDate>Tue, 24 Mar 2026 18:44:13 +0000</pubDate>
      <link>https://dev.to/girma35/starting-point-for-kagglers-customer-churn-prediction-competition-37jj</link>
      <guid>https://dev.to/girma35/starting-point-for-kagglers-customer-churn-prediction-competition-37jj</guid>
      <description>&lt;p&gt;You open the Playground Series S6E3 competition, see 250k+ rows of customer data, and think: “Where do I even start?”  &lt;/p&gt;

&lt;p&gt;I’ve been there. This post is exactly the first notebook I wish I had when I jumped in   a dead-simple, copy-paste-ready pipeline that takes you from raw CSV to a solid submission. No theory overload, just the steps that actually work (and why they matter). Let’s go!&lt;/p&gt;

&lt;h3&gt;
  
  
  1. Grab the Tools
&lt;/h3&gt;



&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;pandas&lt;/span&gt; &lt;span class="k"&gt;as&lt;/span&gt; &lt;span class="n"&gt;pd&lt;/span&gt;
&lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;numpy&lt;/span&gt; &lt;span class="k"&gt;as&lt;/span&gt; &lt;span class="n"&gt;np&lt;/span&gt;
&lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;matplotlib.pyplot&lt;/span&gt; &lt;span class="k"&gt;as&lt;/span&gt; &lt;span class="n"&gt;plt&lt;/span&gt;
&lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;seaborn&lt;/span&gt; &lt;span class="k"&gt;as&lt;/span&gt; &lt;span class="n"&gt;sns&lt;/span&gt;
&lt;span class="kn"&gt;from&lt;/span&gt; &lt;span class="n"&gt;sklearn.model_selection&lt;/span&gt; &lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;train_test_split&lt;/span&gt;
&lt;span class="kn"&gt;from&lt;/span&gt; &lt;span class="n"&gt;sklearn.metrics&lt;/span&gt; &lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;roc_auc_score&lt;/span&gt;
&lt;span class="kn"&gt;from&lt;/span&gt; &lt;span class="n"&gt;sklearn.ensemble&lt;/span&gt; &lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;RandomForestClassifier&lt;/span&gt;
&lt;span class="kn"&gt;from&lt;/span&gt; &lt;span class="n"&gt;lightgbm&lt;/span&gt; &lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;LGBMClassifier&lt;/span&gt;
&lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;warnings&lt;/span&gt;
&lt;span class="n"&gt;warnings&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;filterwarnings&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;ignore&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;These are my go-to imports for every tabular comp. LightGBM will be your hero later.&lt;/p&gt;

&lt;h3&gt;
  
  
  2. Load &amp;amp; Quick Look
&lt;/h3&gt;



&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;df&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="n"&gt;pd&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;read_csv&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;/kaggle/input/competitions/playground-series-s6e3/train.csv&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;span class="n"&gt;X&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="n"&gt;df&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;drop&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;columns&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;Churn&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;id&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;])&lt;/span&gt;
&lt;span class="n"&gt;y&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="n"&gt;df&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;Churn&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;Run &lt;code&gt;df.shape&lt;/code&gt;, &lt;code&gt;df.head()&lt;/code&gt;, &lt;code&gt;df.info()&lt;/code&gt;. Clean data, zero missing values — we’re lucky today!&lt;/p&gt;

&lt;h3&gt;
  
  
  3. Tiny Cleanup (Just in Case)
&lt;/h3&gt;



&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;TotalCharges&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="n"&gt;pd&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;to_numeric&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;TotalCharges&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;],&lt;/span&gt; &lt;span class="n"&gt;errors&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;coerce&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;Always make sure numbers are actually numbers.&lt;/p&gt;

&lt;h3&gt;
  
  
  4. Know Your Columns
&lt;/h3&gt;

&lt;ul&gt;
&lt;li&gt;
&lt;strong&gt;Numbers&lt;/strong&gt;: tenure, MonthlyCharges, TotalCharges, SeniorCitizen
&lt;/li&gt;
&lt;li&gt;
&lt;strong&gt;Categories&lt;/strong&gt;: gender, Contract, PaymentMethod, streaming stuff, etc.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Models only understand numbers, so categories need love.&lt;/p&gt;

&lt;h3&gt;
  
  
  5. My Secret Weapon: Merge Columns
&lt;/h3&gt;

&lt;p&gt;This one trick makes everything faster and cleaner:&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;StreamingAny&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="p"&gt;((&lt;/span&gt;&lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;StreamingTV&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt; &lt;span class="o"&gt;==&lt;/span&gt; &lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;Yes&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt; &lt;span class="o"&gt;|&lt;/span&gt; &lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;StreamingMovies&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt; &lt;span class="o"&gt;==&lt;/span&gt; &lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;Yes&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;)).&lt;/span&gt;&lt;span class="nf"&gt;astype&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nb"&gt;int&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;span class="n"&gt;X&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;drop&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;columns&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;StreamingTV&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;StreamingMovies&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;])&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;&lt;strong&gt;Why I do this every time:&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Cuts 4–5 columns → 20–40% faster training&lt;/li&gt;
&lt;li&gt;Saves RAM (huge on big datasets)&lt;/li&gt;
&lt;li&gt;Removes confusing duplicate signals&lt;/li&gt;
&lt;li&gt;Model learns real customer habits instead of memorizing noise&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Feels like decluttering your code  suddenly everything runs smoother.&lt;/p&gt;

&lt;h3&gt;
  
  
  6. Turn Words into Numbers
&lt;/h3&gt;

&lt;p&gt;Easy Yes/No first:&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;binary_cols&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;Partner&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;Dependents&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;PhoneService&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;PaperlessBilling&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt;
&lt;span class="k"&gt;for&lt;/span&gt; &lt;span class="n"&gt;col&lt;/span&gt; &lt;span class="ow"&gt;in&lt;/span&gt; &lt;span class="n"&gt;binary_cols&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt;
    &lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="n"&gt;col&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="n"&gt;col&lt;/span&gt;&lt;span class="p"&gt;].&lt;/span&gt;&lt;span class="nf"&gt;map&lt;/span&gt;&lt;span class="p"&gt;({&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;Yes&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt; &lt;span class="mi"&gt;1&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="s"&gt;No&lt;/span&gt;&lt;span class="sh"&gt;'&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt; &lt;span class="mi"&gt;0&lt;/span&gt;&lt;span class="p"&gt;})&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;Then the rest:&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;X&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="n"&gt;pd&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;get_dummies&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;drop_first&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="bp"&gt;True&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;All numeric now. Boom.&lt;/p&gt;

&lt;h3&gt;
  
  
  7. Split Smart
&lt;/h3&gt;



&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;X_train&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;X_val&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;y_train&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;y_val&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="nf"&gt;train_test_split&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;
    &lt;span class="n"&gt;X&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;y&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;test_size&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="mf"&gt;0.2&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;stratify&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="n"&gt;y&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;random_state&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="mi"&gt;42&lt;/span&gt;
&lt;span class="p"&gt;)&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;Stratify keeps the churn ratio the same   critical for this competition.&lt;/p&gt;

&lt;h3&gt;
  
  
  8. Train Two Models (Quick Check + Real Deal)
&lt;/h3&gt;

&lt;p&gt;&lt;strong&gt;Baseline (Random Forest):&lt;/strong&gt;&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;rf&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="nc"&gt;RandomForestClassifier&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;random_state&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="mi"&gt;42&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;span class="n"&gt;rf&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;fit&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;X_train&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;y_train&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;span class="nf"&gt;print&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;RF ROC-AUC:&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="nf"&gt;roc_auc_score&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;y_val&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;rf&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;predict_proba&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;X_val&lt;/span&gt;&lt;span class="p"&gt;)[:,&lt;/span&gt; &lt;span class="mi"&gt;1&lt;/span&gt;&lt;span class="p"&gt;]))&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;&lt;strong&gt;The one that actually scores well (LightGBM):&lt;/strong&gt;&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;lgb&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="nc"&gt;LGBMClassifier&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;random_state&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="mi"&gt;42&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;span class="n"&gt;lgb&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;fit&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;X_train&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;y_train&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;

&lt;/code&gt;&lt;/pre&gt;

      <title>The Heart of Machine Learning: Underfitting, Overfitting, and How Models Actually Learn</title>
      <dc:creator>Girma</dc:creator>
      <pubDate>Sat, 21 Mar 2026 06:51:01 +0000</pubDate>
      <link>https://dev.to/girma35/the-heart-of-machine-learning-underfitting-overfitting-and-how-models-actually-learn-2l8j</link>
      <guid>https://dev.to/girma35/the-heart-of-machine-learning-underfitting-overfitting-and-how-models-actually-learn-2l8j</guid>
      <description>&lt;p&gt;Imagine you’re teaching a kid math.&lt;/p&gt;

&lt;p&gt;If the kid just memorizes every single example you give → he aces the homework but bombs the test.&lt;br&gt;
If the kid barely understands anything → he fails both homework and the test.&lt;/p&gt;

&lt;p&gt;That’s exactly what happens with machine learning models.&lt;br&gt;
These three ideas — underfitting, overfitting, and generalization — are the real “physics” behind why some models work in the real world and others don’t.&lt;br&gt;
Let’s break them down in the simplest, clearest way possible (with pictures so your brain doesn’t hurt).&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Generalization – The Only Thing That Actually Matters
Generalization = the model performs well on new, unseen data, not just the data it was trained on.
You train on Dataset A (D_train).
You test on Dataset B (D_test).
If the accuracy is almost the same → great generalization.
If it crashes on the test set → poor generalization.
The model isn’t learning your specific photos, numbers, or sentences.
It’s trying to learn the hidden rules (the underlying distribution) of the world.&lt;/li&gt;
&lt;li&gt;Overfitting – The Student Who Memorized Everything
The model becomes a parrot.
It learns:&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Real patterns ✅&lt;br&gt;
Random noise ❌&lt;/p&gt;

&lt;p&gt;Result?&lt;br&gt;
Training error → almost zero&lt;br&gt;
Test error → sky high&lt;br&gt;
Classic signs:&lt;/p&gt;

&lt;p&gt;Way too many parameters (a huge neural net)&lt;br&gt;
Not enough training data&lt;br&gt;
No regularization&lt;/p&gt;

&lt;p&gt;Think of it as a student who memorizes every past exam question word-for-word instead of understanding the concepts.&lt;br&gt;
medium.commedium.com&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Underfitting – The Student Who Gave Up
The model is too dumb or too lazy.
It can’t even capture the basic patterns in the training data.
You get:&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;High training error&lt;br&gt;
High test error&lt;/p&gt;

&lt;p&gt;Causes:&lt;/p&gt;

&lt;p&gt;Model too simple (tiny linear regression on complex data)&lt;br&gt;
Training stopped too early&lt;br&gt;
Bad features&lt;/p&gt;

&lt;p&gt;It’s like trying to predict house prices using only the color of the front door.&lt;br&gt;

&lt;ol&gt;
&lt;li&gt;Bias–Variance Tradeoff (The Real Engine)
This is the fundamental law.
Bias = error because your model makes wrong assumptions (too simple)
Variance = error because your model is too sensitive to small changes in the training data (too complex)
Here’s the famous picture that explains everything:
oaconn.medium.comConceptualizing the Bias-Variance Trade-Off | by Orin Conn | Medium
Sweet spot in the middle = best generalization.&lt;/li&gt;
&lt;li&gt;The Modern Surprise: Double Descent
Old textbooks said: “More complexity = worse generalization after a point.”
Deep learning laughed at them.
Today we see the double descent curve:
Error goes down → up (classic overfitting) → then down again when the model becomes ridiculously huge.
This is why GPT-4, Stable Diffusion, etc. work at all.

&lt;li&gt;The 4 Pillars That Create Generalization
Generalization doesn’t come from magic. It emerges from four things working together:&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;Data → size, quality, diversity&lt;br&gt;
Model Architecture → right inductive bias (CNNs love images, Transformers love sequences)&lt;br&gt;
Objective Function → loss + regularization terms&lt;br&gt;
Optimization → SGD, Adam, learning rate tricks&lt;/p&gt;

&lt;p&gt;Change any one pillar and the whole building shakes.&lt;br&gt;
Best Books – From Zero to Research Level&lt;br&gt;
Beginner (build intuition)&lt;/p&gt;

&lt;p&gt;Hands-On Machine Learning – Aurélien Géron (practical gold)&lt;br&gt;
Pattern Recognition and Machine Learning – Christopher Bishop (bias-variance explained perfectly)&lt;/p&gt;

&lt;p&gt;Intermediate (theory)&lt;/p&gt;

&lt;p&gt;Understanding Machine Learning: From Theory to Algorithms – Shalev-Shwartz &amp;amp; Ben-David&lt;br&gt;
The Elements of Statistical Learning – Hastie, Tibshirani, Friedman (the bible)&lt;/p&gt;

&lt;p&gt;Advanced / Research (what experts read)&lt;/p&gt;

&lt;p&gt;Deep Learning – Goodfellow, Bengio, Courville&lt;br&gt;
Deep Learning Generalization: Theoretical Foundations and Practical Strategies – Liu Peng (the book that goes deep into double descent, NTK, overparameterization)&lt;br&gt;
Information Theory, Inference, and Learning Algorithms – David MacKay&lt;/p&gt;

&lt;p&gt;Recommended learning order&lt;br&gt;
Géron → Bishop → Shalev-Shwartz → Goodfellow → Liu Peng&lt;/p&gt;

      <title>No, the software developer job isn't dead in 2026 but damn, it's changed more in the last couple of years</title>
      <dc:creator>Girma</dc:creator>

      <link>https://dev.to/girma35/no-the-software-developer-job-isnt-dead-in-2026-but-damn-its-changed-more-in-the-last-couple-4pp5</link>
      <guid>https://dev.to/girma35/no-the-software-developer-job-isnt-dead-in-2026-but-damn-its-changed-more-in-the-last-couple-4pp5</guid>
      <description>&lt;p&gt;I've been watching this space closely (hell, we've all been living it), and the headlines screaming "AI KILLS CODING FOREVER" feel like clickbait from people who never shipped real production code. The truth is messier, more interesting, and honestly a bit exciting if you're willing to adapt. Let me break it down honestly, no hype, no doom scrolling.&lt;/p&gt;

&lt;h3&gt;
  
  
  The Panic Was Real (and Partly Right)
&lt;/h3&gt;

&lt;p&gt;Back in 2024 2025, when Anthropic's CEO dropped that bomb about AI writing 90% of code in months, a lot of us rolled our eyes... until it kinda happened. Tools like Claude Opus 4.6, GPT Codex variants, and agentic frameworks (shoutout to stuff like OpenClaw that blew up on GitHub) let one solid dev orchestrate agents to crank out what used to take a small team weeks. Entry level hiring tanked — Stanford studies showed jobs for 22 25 year olds in software dropping 20% from peaks, junior postings down 60% in spots. Companies shrunk teams: a 2 3 person crew with AI can now handle what 8 10 used to.&lt;/p&gt;

&lt;p&gt;Layoffs hit hard in big tech, and "vibe coding" became a meme for the sloppy, regret filled output when people let agents run wild without oversight. Managers who thought "just hire AI" ended up with mountains of unmaintainable slop — hallucinations, security holes, brittle systems that break in prod. That $61 billion technical debt crisis everyone's whispering about? Not made up.&lt;/p&gt;

&lt;p&gt;So yeah, if your job was mostly boilerplate CRUD, copy paste from Stack Overflow, or being the 10th guy on a ticket queue... that version of "software developer" is on life support.&lt;/p&gt;

&lt;h3&gt;
  
  
  But Here's the Flip: The Job Didn't Die  It Leveled Up
&lt;/h3&gt;

&lt;p&gt;Look at the actual numbers from people who aren't selling fear:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;U.S. Bureau of Labor Statistics still projects ~15 18% growth for software devs through 2034   way above average, adding hundreds of thousands of roles.&lt;/li&gt;
&lt;li&gt;Demand for AI native engineers (folks who orchestrate agents, design systems, evaluate output, handle edge cases AI hallucinates on) exploded. Salaries for seniors with agentic skills carry an 18 30% premium in many spots.&lt;/li&gt;
&lt;li&gt;World Economic Forum and JetBrains surveys: 4 in 10 devs say AI already expanded their opportunities; 7 in 10 expect their role to evolve further in 2026. We're shifting from "code writer" to "system orchestrator"   architecture, agent coordination, strategic decomposition, quality gates.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Peter Steinberger (the OpenClaw guy on Lex Fridman's podcast) nailed it: AI agents will probably replace 80% of traditional apps because personal agents handle tasks better than siloed software. But programmers? They evolve into directors — guiding agents through long sessions, voice prompting, refactoring on the fly, integrating tests, even letting agents self modify safely in sandboxes.&lt;/p&gt;

&lt;p&gt;The skill gap widened, not closed. Bad devs (or lazy ones) get exposed fast — AI makes their weaknesses obvious. Great ones become weapons grade productive. The market rewards thinkers over typists now.&lt;/p&gt;

&lt;h3&gt;
  
  
  What This Means for You in 2026
&lt;/h3&gt;

&lt;p&gt;If you're a good engineer already dipping into agentic coding (like the workflows we talked about  voice prompting, long autonomous runs, self modifying agents), you're in a sweet spot. The future isn't fewer jobs; it's fewer rote jobs and way more leverage for those who adapt.&lt;/p&gt;

&lt;p&gt;Juniors/bootcamp folks? Tougher road  the traditional "grind LeetCode → junior role → learn on the job" pipeline shrank. But if you skip straight to mastering AI orchestration, product thinking, and domain expertise, you can leapfrog.&lt;/p&gt;

&lt;p&gt;Everyone else? Upskill or get comfortable being commoditized. Learn to prompt like a pro, build with agents (OpenClaw, Cursor, Aider stacks), focus on what AI sucks at: real world judgment, security, ethics, cross team empathy, turning business chaos into clean systems.&lt;/p&gt;

&lt;p&gt;Coding isn't dead. Hand writing every line like it's 2015? Yeah, that's fading fast. But engineering  solving hard problems, building reliable things that matter, directing intelligence at scale — that's thriving.&lt;/p&gt;

&lt;h3&gt;
  
  
  Call to Action (Freelancer Focused)
&lt;/h3&gt;

&lt;p&gt;The freelance world is booming for adaptable devs right now — companies need quick, high leverage builds without full time overhead. If you're shipping AI augmented work, clients are paying premiums.&lt;/p&gt;

      <description>&lt;p&gt;Literally, 2026 is the year autonomous AI agents exploded—OpenClaw (formerly Clawdbot, then Moltbot) went viral with hundreds of thousands of GitHub stars in weeks, millions of agents spawning on platforms like Moltbook, and everyone scrambling to run these "Claude with hands" beasts 24/7 without frying their laptops or exposing everything to prompt-injection nightmares. Running it locally? Battery drain, security holes, no mobile access. The fix: cloud deployment. This guide walks you through DigitalOcean's official 1-click droplet setup (from their Feb 2026 tutorial) so you get a hardened, always-on instance in minutes—sandboxed in Docker, firewalled, token-auth'd, and ready to chat via Telegram like it's 2026.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Tech Stack&lt;/strong&gt;  &lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;DigitalOcean Droplets (cloud VM)
&lt;/li&gt;
&lt;li&gt;Docker (containerization + sandboxing)
&lt;/li&gt;
&lt;li&gt;OpenClaw / Moltbot (open-source autonomous AI agent)
&lt;/li&gt;
&lt;li&gt;LLM providers: Anthropic Claude, DigitalOcean Gradient AI, etc.
&lt;/li&gt;
&lt;li&gt;Integrations: Telegram (primary channel), WhatsApp/Slack/Discord optional
&lt;/li&gt;
&lt;li&gt;Web dashboard + TUI (terminal chat)
&lt;/li&gt;
&lt;li&gt;MoltHub (skill marketplace for tools like summarization, browsing)
&lt;/li&gt;
&lt;li&gt;Built-in security: Gateway tokens, UFW firewall, rate limiting, non-root execution&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Step-by-Step Implementation&lt;/strong&gt;&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Spin Up the 1-Click Droplet&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
Head to the DigitalOcean Marketplace → search "OpenClaw" (or "Moltbot").&lt;br&gt;&lt;br&gt;
Select the app → choose region (low-latency pick), size (start with 2GB RAM / 1 vCPU ~$12/mo for smooth agentic tasks), and SSH key (mandatory for security).&lt;br&gt;&lt;br&gt;
Create. Done in ~60 seconds.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;SSH In &amp;amp; Grab Config Info&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
&lt;code&gt;ssh root@YOUR_DROPLET_IP&lt;/code&gt;&lt;br&gt;&lt;br&gt;
The welcome message spits out your gateway URL, token, and commands. Everything's pre-hardened—no manual firewall tweaks needed.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Pick Your AI Brain&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
Enter your API key (e.g., Anthropic) when prompted. The service auto-restarts. Pro move: use a limited-key for cost control.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Chat in the Terminal (TUI)&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
Run the TUI command from the welcome msg.&lt;br&gt;&lt;br&gt;
Test memory: tell it something → exit → come back and ask if it remembers. Persistence just works.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Open the Web Dashboard&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
Hit the gateway URL in your browser → auth with the token.&lt;br&gt;&lt;br&gt;
Monitor chats, channels, skills, logs—all in one dark-mode beauty.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Pair Telegram for Real-World Access&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
Use the CLI script to add Telegram → create bot via BotFather → paste token.&lt;br&gt;&lt;br&gt;
Generate pairing code/QR → scan/message in Telegram DMs. Now your agent lives in your pocket.&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;&lt;strong&gt;Install Skills &amp;amp; Go Agentic&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
From dashboard or chat: browse MoltHub → install summarizer, browser tool, etc.&lt;br&gt;&lt;br&gt;
Test: paste URL → watch it summarize like a pro.&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;&lt;strong&gt;Common Mistakes (and How the 1-Click Saves You)&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Everyone's literally running these agents locally in early 2026—huge security risk (exposed ports, root execution, no isolation). Or manual Docker setups forgetting tokens/firewalls. The Marketplace droplet auto-applies best practices: non-root, rate limits, gateway auth, Docker sandboxing. Skip weak local keys or public dashboards? This setup enforces secure pairing. Bonus: scales easily—no more "my Mac Mini is screaming" memes.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Final Result&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;You've got a production-grade, cloud-hosted autonomous agent: 24/7 uptime, Telegram DM control, persistent memory, extensible skills via MoltHub. Latency stays snappy, costs predictable, security locked down. Perfect for personal use or client automations in this agentic boom.&lt;/p&gt;

&lt;p&gt;(Imagine screenshots here of: droplet dashboard, Telegram convo summarizing an article, TUI memory test, web overview with green health status.)&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Call to Action&lt;/strong&gt;&lt;br&gt;&lt;br&gt;
 Literally building agentic AI setups like this for clients right now—custom OpenClaw extensions, secure cloud deploys, Telegram bots, skill integrations, or full autonomous workflows. As a freelance Full-Stack &amp;amp; AI Automation Developer, I turn these viral trends into bulletproof production systems.&lt;/p&gt;
