BotiGigs: An AI Gigs Marketplace

Samuel Aondo — Tue, 25 Nov 2025 11:04:49 +0000

We built BotiGigs because we watched our agency collapse from freelancer delays.
The Problem We Lived
The scenario: Client calls at 4 PM. Needs website copy by 9 AM tomorrow.
Old approach: Call freelancer. They say "maybe in a week." You either:

Do it yourself at midnight (burnout)
Say no (lose the deal)
Hire expensive agency ($2K for one page)

This was killing us. We were stuck in a cycle of hiring freelancers, managing them, fixing their work, rehiring when they quit. It was exhausting and expensive.
We watched other agencies deal with the same thing. We talked to content creators drowning in writing work. E-commerce owners needing 500 product descriptions with no fast option.
The pattern was clear: People needed copy written. They couldn't wait days for freelancers. They couldn't afford agencies. There was no middle ground.
So we built BotiGigs.
What We Built
BotiGigs is a gigs marketplace where you hire AI agents instead of freelancers.
How it works:

Pick a writing gig (blog post, product description, email, cover letter, resume, etc.)
Describe what you need
Get professional copy in seconds
Use it immediately
Pay per task

Current gigs available:

Blog posts: $12
Product descriptions: $8
Email copy: $10
Sales pages: $25
Cover letters: $15
Resumes: $30
LinkedIn profiles: $20
Scripts: $25
And 10+ more writing task types

We're writing-focused right now. We're building image, video, and audio generation next (same platform, one workflow).
What We've Learned So Far
We've been testing this with real users and here's what's actually happening:
What works:

Agencies using it to say "yes" to more projects (instead of "we're at capacity")
Creators getting 10x content volume without hiring
E-commerce stores handling inventory at scale without freelancer delays
Job seekers getting professional resumes for $30 instead of $300

Speed is real:

Average turnaround: 47 seconds to 5 minutes depending on task
This matters more than we thought. Speed = competitive advantage in business

Quality is fine:

Is it perfect? No. But it's professional-grade and ready to use
Some tweaks needed on 20% of outputs. 80% ready to go
Better than cheap freelancers. Not quite as good as expensive professionals
But it costs 10x less than professionals and delivers instantly

The math works:

Current agency customer: Went from saying "no" to capacity-limited projects → can now say "yes" to everything
E-commerce customer: 500 product descriptions = 2 hours of work instead of 3 weeks
Content creator: 4 blog posts = 1 hour instead of 2 weeks of freelancer waiting

What surprised us:

The emotional relief matters as much as the economics
One agency owner said: "I can finally sleep. No more midnight freelancer emergencies."
Turns out the cost savings are great, but the sanity is the real value

Where We Are Right Now
Launch status: Open beta (free trial available)
What we actually have:

15+ writing gigs live
Deployed and working
Real users using it
Still finding bugs and rough edges
Not perfect but genuinely useful

What we're tracking:

User feedback (daily)
Turnaround times (hitting targets)
Output quality (consistently good)
Cost per gig (profitable already)

What we're NOT claiming:

We don't have 10,000 users (we don't)
We don't have a billion dollar valuation (we don't)
We're not going to "disrupt the freelance industry" overnight (we're not)
Our AI is not magical or revolutionary (it's not)

We're just solving a specific problem for specific people and it's actually working.
Why We're Sharing This Now
We're open beta because we're confident in what we've built but honest about what needs work.
What we need:

Users trying it and telling us what breaks
Feedback on pricing and gig types
Real-world use cases we haven't thought of
People who need this yesterday (they drive the best feedback)

What we're NOT doing:

Blasting ads everywhere
Making fake claims
Overpromising on AI capabilities
Pretending this is perfect

We built this because we needed it. Other people seem to need it too. That's the whole story.

Why I Built an AI Form Generator (And Why Traditional Form Builders Are Broken)

Samuel Aondo — Wed, 05 Nov 2025 08:50:59 +0000

Traditional forms have 68% abandonment rates.
Conversational forms fix this. Here's how.
The Problem
Most forms show everything at once. People see it, feel overwhelmed, and leave.
68% abandonment means you're losing 7 out of 10 potential leads.
The Solution
Conversational forms ask one question at a time. Like texting someone.
People actually complete these.
The Data
I tested conversational vs traditional forms:

Traditional: 32% completion
Conversational: 67% completion

109% improvement.
Why It Works

One question at a time = less overwhelming
Feels like texting = familiar
Mobile-friendly by default
People don't see how long it is
Each answer creates momentum

How Proloom Works
Building conversational forms manually takes hours.
Proloom uses AI. You describe what you need in plain text. AI generates the form instantly.
Input: "contact form for dental office"
Output: Working conversational form
Time: 30 seconds
Why AI
AI understands context. Different businesses need different questions.
You just describe what you need. AI figures out the rest.
Who It's For

Small businesses needing more inquiries
Agencies building client sites faster
Anyone tired of form abandonment

Try It
Proloom is free at proloom.app
Type what form you need. AI generates it. Embed anywhere.
Stop losing leads to bad forms

Building a Watermark Removal API for Sora 2 Videos

Samuel Aondo — Fri, 03 Oct 2025 15:52:26 +0000

I recently shipped an API that removes watermarks from Sora 2 videos while preserving audio quality. Here's what I learned building it.

The Problem

As Sora 2 adoption grows, developers building content tools need programmatic ways to process videos. Watermark removal is a common requirement, but building your own ML pipeline is time-consuming and resource-intensive.

Perfect for:

Content management platforms
Video editing SaaS tools
Automation workflows
Creator tool integrations

How I Built a “Fiverr for AI” – and Why It Might Change Freelance Work

Samuel Aondo — Thu, 25 Sep 2025 07:36:03 +0000

Over the last few months I’ve been experimenting with something crazy:
What if AI agents could actually handle the small freelance tasks we pay people for — instantly, and at a fraction of the cost?

That question turned into 47jobs.xyz
.

The Problem I Saw

I’m a solo builder. Every time I needed:

A quick blog post

A lead list

Some copy rewritten

Simple research

…I’d end up spending hours searching on freelance platforms, messaging back and forth, waiting days for delivery.

Great people, but slow and unpredictable when you just want something done now.

My Experiment

I started wiring up different AI APIs + some automation to see if I could get “agents” to complete typical freelance tasks end-to-end.

To my surprise, it worked. The AI wasn’t just generating text; it was:

Doing research

Cleaning data

Writing copy

Formatting output

And it could do it in minutes instead of days.

So I built a simple web app where anyone can submit a task → an AI agent completes it → you get the result back.

Enter 47jobs.xyz

It’s basically a “Fiverr for AI agents” — but there are no profiles, no negotiations, no waiting.
You just submit your task and get the result.

Instant tasks (blog posts, research, lead lists, copywriting)

Flat, transparent pricing

No hidden fees

First task is free — no credit card required.

Why Share This Here?

I know dev.to has a lot of indie hackers, founders, and devs who need to get small tasks done without breaking their focus.
I built 47jobs.xyz for exactly that use case.

I’d love feedback on:

What tasks you’d want an AI agent to handle.

How you’d want pricing to work.

Any features you think are missing.

Video Editor: Scene assembly & post-processing

Building Zano: A Node.js-like Runtime in Rust

Samuel Aondo — Thu, 07 Aug 2025 23:31:35 +0000

From concept to crates.io - How I built a JavaScript-compatible runtime that brings familiar Node.js patterns to the Rust ecosystem

The Journey Begins

As a developer who loves both JavaScript's expressiveness and Rust's performance guarantees, I've always wondered: "What if we could have the best of both worlds?"

Today, I'm excited to share Zano v0.1.1 - a Node.js-like runtime built entirely in Rust that makes this dream a reality.

Try it now: cargo install zano

Crates.io: https://crates.io/crates/zano

GitHub: https://github.com/sazalo101/zano

What is Zano?

Zano is a high-performance backend runtime that provides a familiar Node.js development experience while leveraging Rust's memory safety and zero-cost abstractions. Think of it as "Node.js syntax with Rust performance."

// This is valid Zano code!
const fs = require('fs')

try {
    fs.writeFile('hello.txt', 'Hello from Zano!')
    let content = fs.readFile('hello.txt')
    console.log('File content:', content)
} catch (error) {
    console.error('Operation failed:', error)
}

The Technical Challenge

Building a JavaScript-compatible runtime in Rust presented several fascinating challenges:

1. Language Design

Creating a parser that understands JavaScript syntax while maintaining Rust's type safety required careful design decisions. I built a custom lexer and recursive descent parser that handles:

Variables (let, const, var)
Functions with parameters and return values
Objects and arrays with familiar access patterns
Control flow (if/else, while, try/catch)

2. Async Runtime Architecture

Node.js's event loop is legendary for its performance. I replicated this using Tokio:

pub struct ZanoRuntime {
    globals: Arc<RwLock<HashMap<String, ZanoValue>>>,
    functions: Arc<RwLock<HashMap<String, Arc<dyn ZanoFunction>>>>,
    modules: Arc<RwLock<HashMap<String, ZanoValue>>>,
}

3. Module System

Implementing require() functionality meant building a complete module resolution system with built-in modules like:

const fs = require('fs')      // File system operations
const http = require('http')  // HTTP client/server
const path = require('path')  // Path manipulation
// Global console object available everywhere

Key Features That Make Zano Special

Familiar Syntax

let user = {name: "Alice", age: 30}
let numbers = [1, 2, 3, 4, 5]

function calculateAge(birthYear) {
    return 2025 - birthYear
}

console.log("User:", user.name, "Age:", calculateAge(1995))

Robust Error Handling

try {
    console.log("Attempting risky operation...")
    throw "Something went wrong!"
} catch (error) {
    console.error("Caught:", error)
}
console.log("Program continues safely!")

Package Management

zano init                    # Creates package.json
zano install lodash         # Installs dependencies  
zano run start             # Runs npm scripts

Multiple Execution Modes

zano script.zn              # Run files
zano -e "console.log('Hi')" # Direct evaluation  
zano -i                     # Interactive REPL

Performance Comparison

Aspect	Zano	Node.js
Memory Safety	✅ Compile-time	❌ Runtime errors possible
Startup Time	⚡ Instant	🐌 ~50ms
Memory Usage	📦 Minimal	📊 Higher baseline
Concurrency	Tokio-powered	libuv-based

Real-World Examples

File Processing Pipeline

// file-processor.zn
const fs = require('fs')

console.log("File Processing Pipeline")

try {
    let data = "user1,admin\nuser2,member\nuser3,guest"
    fs.writeFile('users.csv', data)

    let content = fs.readFile('users.csv')
    let processed = "Processed: " + content

    fs.writeFile('processed.txt', processed)
    console.log("✅ Processing complete!")

} catch (error) {
    console.error("❌ Processing failed:", error)
}

Data Analysis Script

// analytics.zn
let jan = {month: "Jan", sales: 1000, costs: 800}
let feb = {month: "Feb", sales: 1200, costs: 900}

function calculateProfit(record) {
    return {
        month: record.month, 
        profit: record.sales - record.costs
    }
}

let results = [calculateProfit(jan), calculateProfit(feb)]
let totalProfit = results[0].profit + results[1].profit

console.log("Total Profit: $" + totalProfit)
// Output: Total Profit: $500

Technical Architecture Deep Dive

Parser Implementation

The heart of Zano is its parser, built as a recursive descent parser with careful attention to JavaScript semantics:

pub enum Expression {
    Literal(ZanoValue),
    Identifier(String),
    Binary { left: Box<Expression>, operator: BinaryOp, right: Box<Expression> },
    Call { callee: Box<Expression>, args: Vec<Expression> },
    Member { object: Box<Expression>, property: String },
    Array(Vec<Expression>),
    Object(Vec<(String, Expression)>),
    // ... more variants
}

Runtime Execution

The runtime uses Tokio's async capabilities to handle JavaScript's event-driven nature:

async fn evaluate_expression(&self, expression: Expression) -> Result<ZanoValue> {
    match expression {
        Expression::Call { callee, args } => {
            // Handle function calls including member functions like console.log
            let function_name = self.resolve_function_name(callee)?;
            let func = self.functions.read().await.get(&function_name)?;
            func.call(args).await
        }
        // ... handle other expression types
    }
}

Development Lessons Learned

1. Start Simple, Iterate

I began with basic arithmetic and gradually added features. This approach prevented overwhelming complexity and allowed thorough testing at each stage.

2. Embrace Rust's Type System

Initially, I fought against Rust's borrow checker. Eventually, I learned to design with ownership in mind, leading to cleaner, more performant code.

3. Community Feedback is Gold

Testing examples from the README revealed edge cases I hadn't considered. User perspective is invaluable.

4. Documentation-Driven Development

Writing examples for the README helped me understand what the API should look like from a user's perspective.

Performance Benefits in Practice

Here's a simple benchmark comparing Zano to Node.js for a CPU-intensive task:

// fibonacci.zn / fibonacci.js
function fibonacci(n) {
    if (n <= 1) return n
    return fibonacci(n - 1) + fibonacci(n - 2)
}

console.log("Fibonacci(35):", fibonacci(35))

Results (on my machine):

Zano: ~1.2s with instant startup
Node.js: ~1.8s + 50ms startup overhead

Note: This is a synthetic benchmark. Real-world performance varies.

What's Next for Zano?

The v0.1.1 release is just the beginning! Here's what's planned:

Version 1.1.0

[ ] Full async/await support with proper Promise handling

What Excel features are absolutely essential for team collaboration workflows?

Samuel Aondo — Sat, 26 Jul 2025 14:21:58 +0000

I've been developing a web-based spreadsheet application focused on real-time collaboration, and I need input from experienced Excel users about feature
priorities.

Background: I'm a software developer who's used Excel for years but primarily for personal projects. My team frequently struggled with Excel's collaboration
limitations (version conflicts, file locking, etc.), so I built a prototype web application to address these issues.

Current feature set:

Standard formulas (SUM, VLOOKUP, INDEX/MATCH, etc.)
Real-time collaborative editing with live cursors
Charts that update as data changes
CSV/XLSX import and export
Data validation and conditional formatting
Basic automation triggers

What I'm missing and need guidance on:

Pivot Tables - How critical are these for your daily workflows? Are there specific pivot table features that are deal-breakers if missing?
Advanced Functions - Beyond the basics, which Excel functions do you consider essential? I'm seeing requests for XLOOKUP, FILTER, dynamic arrays.
Macro/VBA equivalent - For automation, would JavaScript-based scripting be acceptable, or is VBA compatibility crucial?
Data connectivity - How important is direct connection to external data sources (SQL, APIs, etc.) versus manual import/export?

My specific question: If you had to rank Excel features by importance for team-based work, what would be your top 5 must-haves?

I've researched Excel's feature set extensively, but I want to understand real-world usage patterns from this community before prioritizing development time.

Demo available at: sheet-alpha.vercel.app (if anyone wants to test current functionality)

Looking for honest feedback about what makes Excel indispensable for your workflows. Thanks for sharing your expertise.

🛡️ Building an AI-Powered Email Spam Detector: From Concept to Cloud Deployment

Samuel Aondo — Fri, 25 Jul 2025 11:24:26 +0000

A journey through machine learning, web development, and the challenges of detecting sophisticated phishing attacks

🎯 The Problem: Sophisticated Phishing is Winning

Email spam has evolved. Gone are the days of obvious "Nigerian prince" scams filled with typos and broken English. Today's phishing attacks are sophisticated,
professional, and terrifyingly convincing:

Bank of America: Suspicious activity detected on account ending 4567.
Verify at secure-boa-verification.net within 48 hours.

This looks legitimate, right? It's the kind of email that fools even tech-savvy users. Traditional spam filters often miss these because they focus on obvious
spam keywords rather than subtle deception patterns.

That's the problem I set out to solve.

🧠 The Solution: Explainable AI for Email Security

I built an email spam detector that doesn't just say "this is spam" – it explains why and how it detected the threat. Think of it as a cybersecurity teacher that
protects you while helping you learn to spot threats yourself.

Key Features:

Sophisticated Phishing Detection: Specifically targets authority impersonation and domain spoofing
Explainable Results: Shows flagged keywords and detected patterns
Real-time Analysis: Sub-50ms response times
Educational Value: Helps users learn to identify threats

🔬 The Technical Journey

Phase 1: Research and Feature Engineering

The secret sauce wasn't in choosing the fanciest algorithm – it was in understanding how modern scams work. I analyzed hundreds of phishing emails and identified
key patterns:

Authority Impersonation Patterns:
authority_keywords = [
'irs', 'federal', 'government', 'medicare',
'bank of america', 'paypal', 'amazon', 'wells fargo'
]

Threat Language Detection:
threat_patterns = [
'arrest', 'warrant', 'suspended', 'restricted',
'compromise', 'detected', 'breach'
]

Domain Spoofing Recognition:
suspicious_domains = [
'secure-', 'verify-', '-verification',
'-update', '-portal'
]

Phase 2: Building the Detection Engine

I started with a full machine learning approach using scikit-learn:

class SpamDetector:
def init(self):
self.vectorizer = TfidfVectorizer(
max_features=5000,
ngram_range=(1, 2), # Unigrams and bigrams
stop_words='english'
)
self.model = LogisticRegression(
C=1.0, # L2 regularization
solver='liblinear'
)

But here's where it got interesting. I discovered that a well-designed rule-based system could be just as effective and much more explainable:

def detect_sophisticated_phishing(self, text):
score = 0
flags = []

  # Authority + Threat + Domain = High Risk
  if (self.has_authority_reference(text) and
      self.has_threat_language(text) and
      self.has_suspicious_domain(text)):
      score += 50  # Major red flag
      flags.append('sophisticated_phishing_detected')

  return score, flags

Phase 3: Web Interface Design

The frontend needed to be both powerful and accessible. I built a clean, modern interface that shows results progressively:

function displayResults(result) {
// Show classification with confidence
document.getElementById('classification').textContent = result.classification;
document.getElementById('confidence').textContent = result.confidence;

  // Visual probability bar
  const probabilityBar = document.getElementById('probabilityFill');
  probabilityBar.style.width = result.spam_probability + '%';

  // Explain the decision
  displayFlaggedKeywords(result.flagged_keywords);
  displayCustomFlags(result.custom_flags);

}

🚧 Deployment Challenges (And How I Solved Them)

Challenge 1: The 40-Minute Build Problem

My first deployment attempt was a disaster. The cloud platform took 40+ minutes trying to compile scikit-learn and numpy from source:

Preparing metadata (pyproject.toml): still running...
Preparing metadata (pyproject.toml): still running...
Preparing metadata (pyproject.toml): still running...

Solution: I created a lightweight version using pure Python with carefully crafted rules. Deploy time: 2 minutes instead of 40.

Challenge 2: Maintaining Accuracy Without ML Libraries

Could a rule-based system match ML performance? Surprisingly, yes! The key was sophisticated pattern combinations:

def calculate_spam_probability(self, features):
# Weighted scoring system
weights = {

Challenge 3: Making AI Decisions Transparent

Users need to understand why an email was flagged. I built a comprehensive explanation system:

const explanations = {
'authority_impersonation': 'Email claims to be from a bank or government agency',
'domain_spoofing': 'Suspicious domain that mimics legitimate services',
'threat_language': 'Uses threatening language to create urgency',
'phishing_language': 'Contains common phishing phrases'
};

🎯 Results That Matter

The final system successfully catches sophisticated threats:

Test Case: Bank Phishing
Input: "Bank of America: Suspicious activity detected on account ending 4567.
Verify at secure-boa-verification.net within 48 hours."

Output:
✅ 87% Spam Probability
🚩 Flags: authority_impersonation, threat_language_detected, domain_spoofing_detected
📝 Explanation: "Impersonates Bank of America with threatening language and fake domain"

Performance Metrics:

85%+ accuracy on sophisticated phishing
<50ms response time
<15% false positive rate on legitimate emails

💡 Key Lessons Learned

Feature Engineering > Algorithm Choice

The magic wasn't in using the latest neural network – it was in understanding the problem domain deeply and crafting features that capture real threat patterns.

Explainability is a Feature

Users don't just want protection; they want to learn. Making AI decisions transparent builds trust and helps users recognize threats independently.

Deployment Constraints Drive Innovation

The 40-minute build problem forced me to rethink the entire approach. Sometimes constraints lead to better solutions.

Rules Can Beat ML (Sometimes)

For well-understood domains like spam detection, carefully crafted rules can match ML performance while being faster, more explainable, and easier to deploy.

Legitimate email: "Hi John, let's schedule our coffee meeting for tomorrow at 3pm."

🔮 What's Next?

This project opened my eyes to the potential of hybrid AI systems that combine the best of rule-based and machine learning approaches. Future enhancements could
include:

Real-time learning: Adapt to new phishing patterns automatically
Browser extension: Integrate directly with email clients
Multi-language support: Detect scams in different languages
Advanced visualizations: Show threat patterns graphically

🎓 The Bigger Picture

Building this spam detector taught me that effective AI isn't always about the most complex algorithms. Sometimes the best solution is:

Understanding the problem deeply
Designing features that capture real patterns
Making decisions transparent and educational
Optimizing for real-world deployment constraints

The cybersecurity field needs more tools that don't just protect users but educate them. This project is a small step toward making the internet safer through
both automation and human understanding.
