Hey everyone! 👋
I'm Abhi, a B.Tech student and developer from India.
I'm here to learn, build, break things, and hopefully contribute to the community along the way.
Currently working with Python, AI, backend development, and open source. I'm also building a developer tool called Spawn to make repetitive Python project setup a little less painful. 🐍
Looking forward to learning from everyone here and meeting some fellow builders! 🚀
Hi Abhi! 👋 Nice to meet you. I'm also working with Python, AI, and automation, so Spawn caught my attention. Automating repetitive project setup sounds really useful. Looking forward to seeing how the project develops. 🚀
Thanks Leoncio! Nice to meet a fellow Python/AI/automation person 🙌 Would love your thoughts once you've had a chance to poke around Spawn. Always looking for feedback from people working in that space.
pip install spawnio - it is
nice, welcome aboard
Hello!
Hello everyone
I'm a teacher from Palestine who loves tech. I'm not a coder myself but i have a desire to learn and build apps that suit my own use cases. And since i can't really code and don't have the time to learn i've went down the ai coding route. I'm always ready for advice. Nice to meet you all .
Apps that suit your own use cases is the category where this actually works. Which project you pick first matters more than the coding, though. I have a home automation setup I built this way and have never read a line of its code - fine, because when it breaks I flip the switch by hand. Anything where a bad result costs me something, I still end up reading what the model wrote.
Start with something where a bug is only annoying. What are you building first?
I am building a site for wife that documents her 'antique' items for her 'store'. She needs something to track storage location and history. I hope to have this ready for her by the time I reach the upswing of awesome.
That sounds interesting , building a physical tracking app would be very helpful for her for sure. And the history function i think would be good , maybe create a tag system to make things easier to manage. Also a storage location history , in case something goes missing you will have information at every storage location it has ever been at.
I agree, having something personalized to your own use case and fits your vision is the best category where coding using ai works best. It doesn't have to be perfect and you can make it fit your use case perfectly if you give yourself enough time to actually use the app you're building and debug it. However, bugs can be hard to debug for noncoders like me and ai isn't at the stage where there won't be any bugs or errors in the outcome. I've made a small dictionary app where students can upload a pdf/doc/txt file to the app and it would auto translate every English word into Arabic with English meaning, synonyms and antonyms. I'm also building a personal media library app (but that's a pretty huge app I've been building for the past six months.). Honestly , speaking the biggest friction i have with coding using ai is the structures ai build the app on. It seems that ai always uses the easiest or shortest path which may not mean the best approach or structure to build an app on. I've faced this with the library app I'm making and right now I'm in the middle of redoing the structure of the app. Being a non-coder means i don't know the terms or the structures best suited for the apps i'm building and ai is doing a really bad job at giving advice in this regards. So I've learnt my lesson for future apps i plan to make, first research the structure to build upon and map things out correctly.
I'm also curious about automation , i haven't done it outside of the apps I've built so far. I've heard a lot of people talk about creating a workflow for coding which i haven't done yet. What's the a home automation setup you made ? And how did you build it ?
I don't really use automations for coding. Claude Code is a good level of automation for me out of the box. My monitoring are about monitoring, and some routines. My loop agent checks the logs of my apps in prod, collects user metrics, checks API budgets and other thing. Then it lets me know in Telegram.
Hi everyone! 👋
I'm Andrew, building PromptSpend, an open-source LLM cost calculator that tries to get the actual arithmetic right (compounding chat history, cache-write costs, promotional pricing that expires, that kind of thing), backed by a catalog that re-checks itself against vendors every morning.
Just published my first piece here, about the specific ways pricing calculators like mine get the number wrong, including one we got wrong ourselves, in public, on our own product.
Excited to be part of the community and see what everyone's building.
Publishing the one your own tool got wrong is rare. The gap I keep hitting sits upstream of the arithmetic though - you cannot know the output length before the call. I track cost per call on a side project that runs a lot of models, and on thinking models about 60% of billed output turns out to be reasoning, roughly a 2.5x multiplier over the visible answer, and it moves run to run.
So I stopped projecting single requests and bound the session instead: models are banded by effective output price, and the band decides how much can run. Does PromptSpend take a reasoning estimate from the user, or carry a per-model multiplier?
Good question, and the honest answer is user-supplied, not a per-model default. PromptSpend has a reasoning-multiplier field, defaults to 1x, that you set yourself — it bills output at round(output_tokens x multiplier). The model catalog only flags whether a model has hidden reasoning at all, a boolean, not how much; the multiplier isn't derived from anything because there's no published per-model figure to derive it from, and it swings run to run like you said. Your 2.5x number is a genuinely useful data point, closer to a real per-model default than what's in there today, which is just 1x until someone moves the slider.
PromptSpend sounds really useful, especially with how messy LLM pricing has become.
I really like that you're sharing where the calculator itself got things wrong too. That kind of transparency makes technical projects way more interesting to follow.
I'll definitely check it out 👀
Thanks, Abhiix0! Appreciate you reading through the calculator's own mistakes too — that was almost the part I cut, but it's the part that actually matters. Let me know if you hit anything weird once you try it.
Glad you kept that part in—it definitely gives great context. I’ll run some tests with it soon and let you know if anything pops up. Cheers!
Hello, everyone! 👋
I’m Asada Shinsaku, a software engineer who loves coding—sometimes more than my code loves compiling.
I’m really happy to be here. This community already feels warm and welcoming, and I’m looking forward to meeting you, seeing what you’re building, and sharing the occasional debugging headache.
I hope we can support one another, help our projects grow, and celebrate those rare, magical moments when everything works on the first try.
Thanks for having me. I’m excited to be part of the community!
Haha, "sometimes more than my code loves compiling" is painfully relatable 😂
Welcome! Looking forward to seeing what you're building too. Hopefully we get more of those magical "works on the first try" moments than debugging headaches here 🚀
Thank you for your kindness.
I hope we can discuss more work matters in the future.
Thank you once again.
Welcome! I'm new here too.
Thank you! ♥️
Hey Asada, welcome! Excited to see what you build and share here! 🙌
Hi, I'm Robert, and I'm a software engineer. I'm here to engage with the community around the stuff I'm prototyping - which is currently Tauric Studio, a Tiled-compatible map editing tool for game developers.
Hi everyone! 👋
I'm Leoncio from the Philippines. I work with Python automation, web scraping, data pipelines, and AI-assisted workflows.
Recently, I've been building practical tools around web data extraction and business automation, including Apify Actors and small systems designed to reduce repetitive manual work. I'm especially interested in turning real-world workflows into reliable, maintainable software.
I'm here on DEV to keep learning, document what I discover while building, and learn from developers working on automation, AI, backend systems, and data engineering.
Looking forward to meeting fellow builders and sharing what I learn along the way! 🚀
Hey everyone! I'm Abrham from Ethiopia.
I'm a developer who loves building creative projects and learning new things.
Outside of coding, I'm a huge movie fan -- I love getting lost in a good story, discussing plot twists with friends, and discovering new perspectives.
I'm always up for a great conversation and love learning something new from every person I meet.
Nice to meet you all!
Hi everyone! 👋
I'm an engineer and independent researcher. I recently built a lightweight, local-first RSS reader to bypass Reddit's strict unauthenticated API rate limits (using a combined "hot" feed workaround).
I joined DEV to share technical learnings from that process, read about open-source workflows, and connect with fellow developers. Looking forward to the discussions and great articles here!
Hey everyone! 👋
Recent grad here — just joined a company that works heavily in AWS, and I'm learning backend development on the job (Node.js/TypeScript, Lambda, API Gateway, PostgreSQL, and the AWS ecosystem more broadly). Landed here to learn from people further along than me and hopefully share what I pick up along the way too.
Fun fact: I'm still at the stage where every new AWS service I touch feels like unlocking a new level 😄
Looking forward to being part of this community!
Hi everyone! 👋

Hello, colleagues!
Glad to be part of this friendly community of enthusiasts.
I've already published an article here about my debugging tool for coding agents. I hope you found it useful. Giving agents X-ray vision—that was worth all the effort.
And now I have some big ideas. I've been searching for a long time and found a way to provide agents with information in the most convenient format. But that's the topic of the next article. I just finished it and am about to publish it. Enjoy!
Hi everyone,
I am Seth, a graduate student, and most of what I build is a re-implementation of something which already exists, since rebuilding systems seems to be the only reliable way that I have found to learn which parts of its design are actually load-bearing.
What I worked on most recently is a Kubernetes API server in Node that the real
kubectltalks to unmodified, a macOS browser (Swift, onWKWebView) that holds a memory budget you give it the way a game engine holds a frame budget, a web crawler that implements the B25 algorithm, and a benchmark that ranks language models on catching liars in a game of Mafia instead of on win rate.What keeps me interested is that the failure is never in the part I expect. I priced a hibernated browser tab at 32 KB in simulation; real WebKit charges 39 MB. My web crawler's rate limiter measured itself as enforcing a perfect five-second delay while the host on the other end was receiving a hundred requests at once. However, in both cases every component was correct and the composition was wrong, which is hard to catch from inside a single process.
I have been documenting most of my findings from my projects at sethwheeler.dev, and cross-posting my findings here. Glad to be here.
Hi everyone! 👋
I'm Kyohei, an independent developer from Japan building simple, privacy-focused tools for macOS.
I recently released SnapSlim, a native Mac app for compressing JPEG, PNG, and HEIC images entirely on-device, and I joined DEV to share what I learn while building and shipping small software products.
I'm especially interested in macOS development, local-first software, developer tooling, testing, and AI-assisted development.
I just published my first post here today. Looking forward to learning from everyone and sharing more along the way!
Nice to meet you all! 🐈
welcome nice to meet u i wish u a great day
Thanks! Nice to meet you too, have a great day!
Hi everyone! 👋
I’m Akira, an AI/ML Engineer based in California. I’ve been working in software engineering and machine learning for several years, with most of my recent work focused on LLM applications, generative AI, RAG, NLP, and building AI systems that actually make it into production.
I joined DEV because I want to learn from other developers, share some of the things I’ve learned along the way, and hopefully contribute to some interesting discussions.
I’m particularly interested in AI engineering, LLM infrastructure, model evaluation, AI agents, and the practical side of taking ML systems from an idea to something people can actually use.
Looking forward to meeting everyone here and reading what you’re building. Feel free to say hi! 🚀
Hey guys! ~
I’m Valentine, a solo founder building MORPHOICES — an AI-powered product development system for turning scattered ideas into structured, launch-ready digital products.
What brought me here is a problem I keep running into while building: context gets lost as work moves between tools and stages.
Research lives somewhere.
Decisions end up in docs.
Implementation happens somewhere else.
Then a few weeks later, you’re trying to remember ''why'' you made a particular decision in the first place.
I’m exploring how AI can work inside a system that keeps those connections intact — from research and decisions through validation, planning, and execution.
I’m still learning a lot about product architecture, AI workflows, and what actually makes these systems useful in practice.
Looking forward to learning from everyone here and meeting other builders. 👋
Hey everyone, I'm Peter. I'm building PDFHaul, a free browser-based PDF toolkit, solo.
Most of what I've been deep in lately is PDF parsing and table extraction, which turns out to be a much harder problem than it looks once you get past simple bordered tables. I recently shipped an MCP server for it too, bcrypt-hashed API keys, JWT, SSRF prevention, idempotency keys, the works, which taught me more about the edge cases of letting AI agents touch real files than I expected going in.
Happy to talk PDFs, document processing, MCP, or the general chaos of building something solo on nights and weekends. Looking forward to seeing what people here are working on.

👋 Hi everyone! I'm Mohammed, a software engineering student from Yaounde international business school.
I'm currently learning React, Node.js, and full-stack web development by building YouthTrend, a student network platform for connecting campuses across Cameroon — feed, communities, events, and projects, all in one app.
Excited to be part of this community, learn from other devs, and share progress as the project grows. Feel free to say hi!
Hi, I’m Ajoy, a Software Engineer with around 3 years of experience, primarily working with Java, Spring Boot, and backend systems.
I’ve worked across enterprise applications, developer tools, reporting systems, automation workflows, and data-driven applications, with a focus on building scalable and maintainable solutions.
I’m particularly interested in system design, databases, distributed systems, performance engineering, and AI/ML, and I enjoy exploring these areas through side projects and open-source work.
"Hey everyone, Checksum here. I build workflows for AI agents and spend way too much time thinking about how to stop them from failing silently. My current obsession is deterministic checks and stopping verifiers from getting gamed. Say hey if you want to geek out over confident AI failures."
👋 hello,

Hi everyone, I'm str-int-float. I'm a hobbyist programmer who loves technology. I've built a lightweight Agent platform for small models running on personal computers, which helps them handle complex tasks more effectively. The project is open-source. I'm looking forward to learning from and exchanging ideas with all of you here, and growing together.
Hi everyone,
I build small, static, no-account web tools — most recently a calculator site (finance, health, unit conversion, that kind of thing), all client-side, no backend, statically generated. I got here because I wanted to write up a few of the architecture decisions that came out of building it — mostly around when a backend is actually justified vs. when it's just the default shape people reach for.
Looking forward to reading and sharing more here.
Hey everyone! 👋
I'm Tomasz, a Polish dev who's been surviving in the UK for almost 20 years now (yes, I still can't get used to the weather).
By day, I'm a freelance web developer building fast websites for local businesses. By night, I'm building AI-powered tools to automate my life with Claude Code, multi-agent systems, and whatever new shiny thing catches my attention.
Think Batman, except I'm not a millionaire and definitely don't wear a cape. Just sweatpants and too much coffee 😂
Fun fact: I once spent 3 hours optimizing a site to get a perfect 100/100 Lighthouse score. The client never noticed but still worth it.
Looking forward to sharing my experiments (and failures) with this community!
Hey everyone! I'm Aarush Karak — a high school software developer from Toronto, Canada, focused on spatial computing, AI, and full-stack development.
I'm the founder of TheCoderBros, a platform engineering fellow at Hack Club (Stardance), and a 1st-place TSA State Champion in Video Game 3D Design. I love building at the intersection of the web and 3D — my favorite project is HELIOS, a browser-based AI operating system with hand-gesture navigation built on Three.js and MediaPipe.
My blog covers spatial computing on the web, React Server Components, PostgreSQL internals, and CLI tooling — plus the occasional deep dive into my open-source projects like astro-tasks (a Python CLI developer dashboard, shipped on PyPI).
You can find me at aarushkarak.vercel.app or on GitHub @3ni8ma. Excited to be here and happy to connect!
Please I want to learn full stack development please who can help and one problem is I’m 14years
Hi, I'm Panagis. I spent my summers on a Greek island and got tired of civil protection alerts arriving by SMS while satellite data was free.
So I started building ARGOS : : Kefalonia Digital Twin an open-source digital twin of the entire island from my laptop, using PostGIS, Sentinel-2, and very busy afternoons schedule.
The first thing the model found was a lighthouse nobody asked about. I wrote about how it happened:
dev.to/ptzivras/i-built-a-digital-...
If you know geospatial stacks, Mediterranean fuel models, or just like maps that argue back, I'd love to hear from you. 🗺️
Hello everyone!
I'm a solo backend developer with a strong passion for DevOps. I'm currently building NuxiPro, a SaaS designed to declutter our Kanban workspaces from completed tasks.

Hi everyone! Matheus here, I am a mobile dev, software engineer student and in my free time I took lots of photos and ride my motorcycle. Looking forward to learn and keep up with the news and novelties about our professional subjects.
Hi everyone! 👋 I'm Alexander, a developer working mostly around AI coding workflows and open-source tooling. I'm currently building DeskCue and experimenting with how tools like Codex, Claude Code, and local models fit into everyday development.
Joined DEV to share what I'm learning along the way and to learn from what others are building here. Nice to meet you all!
Hi everyone 👋
I'm Nitish, a backend engineer from Mumbai — six years mostly in Ruby on Rails. I currently work on a workplace learning platform, where my time goes on API design, database performance, and shipping LLM-backed features.
What brought me here: I wrote up a debugging story from work — a reporting page taking 78 seconds to load, four existing indexes that didn't help, and the covering index that fixed it. Writing it out clarified my own reasoning more than I expected, so I plan to keep doing it.
Fun fact: the most satisfying thing I've written this year was six column names in the right order.
Hello, DEV! 👋
Finally joining the DEV community! 🚀
I work mainly around DevOps, cloud infrastructure, and platform engineering, and I’m here to learn, share ideas, and connect with people working on similar things.
Looking forward to being part of the community! ☁️💻
welcome
Hi everyone, I'm Fibula.
I spent the last ~8 months making a ten-episode AI film series, using Claude
Code as the production crew. I'm a cloud DevOps engineer by day, so it also
turned into a software project: validators and a CI gate that check creative
work instead of code.
Just posted my first article here, about a test that reported PASS while the
file it was checking was broken.
Still figuring out how to test output that comes out different every time. If
you're doing something similar, say hi.

Hello!
I am Maki. I got into the software development ever since the age of 10. I had multiple motivations back then - one of them being my father who was a hero to me. He was always able to repair the computer that I've broken by downloading free computer games, which was mind-blowing to me back then.
Another motivation was the fact that I loved playing computer games such as Heroes: Might & Magic III, WoW, etc. I also loved to watch the tv show Star Gate. I loved how they have managed to save the world by understanding a computer program minutes before disaster.
So I decided that I also want to save the world by helping others, as well as making my father proud and perhaps one day - become better. And it paid. The gift that was given to me by the universe started to pay off - persistence.
I spent years of studying on my own, creating projects, working for companies bigger and smaller and step by step becoming better in what I do.
At some point I have reached level where I can tell that I made by father proud and now - the other goal remains - make this world a better place.
Thank you!
Hey everyone, Carl here. I build fast, static content sites in vanilla PHP and syndicate them to Pinterest. I just open-sourced a small piece of that: syndikit-pin, a zero-dependency library that turns a photo and a title into a Pinterest pin. I'm here to share what I learn building in plain PHP with no frameworks, and to pick up tricks from all of you. Fun fact: I run my whole stack with no terminal, just a browser and cPanel, which forces some creative solutions. Glad to be aboard.
welcome Carl i hope u have a great time here
Hi all! I am full-stack web developer.
Started many years ago with simple HTML/CSS pages, then mastered WordPress, which became my favorite for a long time. Later, immersed myself in exploring Laravel, and quite recently, my learning journey led me to mastering React.
I’m not a vibecoder, but I’m actively studying ways to turn AI into a good assistant.
welcome :)
Hi everyone!
I’m a software engineer currently working from Vancouver, Canada.
I recently started writing about lessons and reflections from my day-to-day engineering work. I’m hoping to use writing as a way to organize my thoughts, deepen my understanding, and share what I learn along the way.
Looking forward to learning from everyone here!
Hello everyone! 👋
You can read this even though I couldn't have written it in English on my own. But what if I had written it in Chinese? Would that have stopped you from understanding it? Probably not. You could simply translate it and understand what I meant.
I don't speak Chinese either, but with the help of AI, I could probably write an article in Chinese too. And why not? :)
I’m Ozco.
I’m not an engineer or an expert; I’m just a curious person. My background is in journalism—a profession fueled by curiosity. I transitioned from reporting to video content creation, and then artificial intelligence entered our lives.
That was exactly when my curiosity was reignited.
And while trying to shape my career around it, I somehow found my way to this site. :)
What's up, Kubernauts? 👋
Kestrion here. I joined DEV to share practical Kubernetes lessons and experience for small and medium-sized engineering teams—especially those running production workloads without a dedicated platform team.
I'm interested in the unglamorous but important parts: safe deployments, tested restores, sensible costs, upgrades, and keeping platform complexity proportional to the size of the team.
Lately, I’ve been wrestling with Karpenter and Istio. Those two never seem to sleep—and apparently, neither do I :-D .
I'm also here to learn from how other teams approach these problems. What cloud-native challenge is taking most of your time right now?
Fun fact: I also maintain a free CKA study project in Spanish.
Very quick question: AWS or Azure?, don't fight for it.
Hi everyone! 👋
I'm Katsuhiro, an engineer from Japan. I've been writing technical articles in
Japanese for a few years, and I've just started publishing English versions
of them here.
Most of what I work on these days is the workflow around AI coding agents —
how to hand work to them without losing track of what's protected, and what
kind of documents are worth keeping when an agent writes most of the tests.
I also spend a lot of time in a terminal-only setup (NixOS, tmux) and
occasionally build small hardware things with a Raspberry Pi.
English isn't my first language, so writing here is partly practice.
Looking forward to reading what everyone's building!
Nice, I’ve been exploring a lot of the same stuff lately around coding-agent workflows and orchestration. Curious to see what you end up writing about.
Hi everyone 👋
I'm Heinrich, building from Germany. I work on cachly — persistent memory for AI coding agents over MCP, so your assistant stops re-reading the codebase every morning.
What actually brought me here: I've learned more from three articles on this site in the last week than from weeks of my own guessing. One post made me rewrite how we store knowledge; another made me rip out a whole error-message convention. So I'd like to give some of that back.
What I'll write about is mostly the stuff that broke, with the numbers attached — a test gate that had silently checked nothing in 50 of its last 64 runs, a stored lesson whose decisive fact sat at character 323 of a 100-character preview. The failures are more useful than the wins, and nobody posts them.
One thing I'm genuinely curious about, since a lot of you are building agent tooling too: how do you know your agent actually used the context you gave it — as opposed to it merely being in the window? We measure it now and the answer was humbling.
Nice to be here.
Hello everybody, I'm Rom . i'm building a few different apps mostly targeting developers and parents. basically building something for myself and hoping everybody else would use it. for example i started devtoolsdaily.com many years ago just b/c I wanted to do simple json format without watching ads. and slowly piled in more and more tools into that. these days I added interview prep (b/c i forgot how to code after I started using claude/codex daily). also many parent oriented apps related to organizing kids art/photos and learning music theory. I blog periodically and hoping that dev.to is a better target audience than general medium one.
Hi everyone! I'm Valerii — I audit algorithmic trading bot code for a living: entry/exit logic, order management, risk handling, fee-honest backtests. Before offering this as a service I audited my own live bot the same way, and I've since filed 40+ public responsible-disclosure issues against open-source trading bots, looking for code that behaves differently than the README or the backtest claims it does. Just started sharing some of the recurring bug patterns here — glad to be part of the community!
Hi everyone!
I'm Andre, a full-stack developer working mainly with React, Next.js, Tailwind, and Shadcn UI. Currently building PatientCare, a patient management system, and I just finished writing a two-book series on AI-assisted development — teaching the fundamentals first, then bringing AI tools into the workflow once there's something solid to judge them against.
Excited to be here, read what people are building, and join the conversation on how AI is actually changing (or not changing) the way we write code day to day.
Looking forward to being part of this community!
Hi everyone! 👋
I'm Misha, a fullstack developer from Saint Petersburg. Mostly working with Python (FastAPI, asyncio) on the backend and React/React Native on the frontend.
Right now I'm building SpeakWise AI, a mobile app for practicing English conversation with voice input and AI feedback - solo project, learning a lot along the way about payments, notifications, and all the edge cases that only show up once real users hit them. Also currently looking for a remote role.
Joining DEV to learn from other builders and share some of the technical stuff I run into.
Outside of code: anime, retro gaming, and a slightly too serious 3D printing hobby.
Looking forward to reading what everyone's working on! 🚀
Hi I’m Daniel , a beginner in software engineering trying to navigate the bad tech education in my country with ai but it’s not been easy since it tends to do all the work, I just recently created my first api site for obtaining second phone numbers and I have a little bit of php yii2 and laravel and trying to learn more , I got recommended here by Gemini after it recommended that I send my website here for checking and reviews ….. callyconnect.com

Hi all, Im a data engineer working with AWS, Snowflake and other databases, Python. I build data pipelines and solutions around AI. Not really building anything of my own at the moment, just looking for contract work.
Hi everyone!
I build practical automation tools, browser extensions, and small open-source experiments. I joined DEV to share what I learn while building them. Most recently, I created a local C2PA Content Credentials validator using Google's Credentio library.
I'm interested in AI automation, open source, content provenance, and product engineering. Looking forward to learning from the community and connecting with other builders!
Hey everyone.
I'm Chris, a systems engineer and web developer from Germany. I build cloud infrastructure and TypeScript applications by day, and pave actual patios and run electrical cables by evening. Same problem-solving mindset, very different tools.
Tech stack is mostly TypeScript, React, Astro, AWS, and Docker. I self-host what I can on Proxmox and automate what makes sense.
I'll be writing about practical patterns and architecture decisions from my projects.
Looking forward to seeing what everyone's building.
Hello!

Hey everyone! 👋 I'm Sheshank, a builder and full-stack developer from India. I enjoy identifying real-world problems and turning them into practical software products. I'm currently building ESOP Value Clarity, a product focused on helping startup employees better understand the potential value of their equity. Excited to learn from the community, share what I'm building, and connect with other builders!
Hey everyone — I'm a uni student from Pakistan, still learning programming (mostly Python right now), and I mostly build small projects for the fun of it, not because they're groundbreaking or anything.
Hi everyone, I’m Louis, A Book.
I’m a data engineer with a background in quantitative finance, where I worked on data infrastructure, backtesting, real-time trading systems, and large-scale data processing.
After spending a few years away from the industry, I’m now rebuilding my technical stack and moving increasingly toward AI and modern data engineering. I’m particularly interested in the intersection of data infrastructure, AI systems, and real-world applications.
I’ll mainly be writing about things I’m learning and thinking about along the way: data engineering, AI, software engineering, technology, and occasionally the broader effects of technology on work and society.
I’m less interested in writing “how to become an AI engineer in 30 days” posts and more interested in understanding how these systems actually work, where they fail, and what they mean for the people building and using them.
Looking forward to reading what others here are working on.
Hi everyone, I’m Sujan, a developer and M.Tech Computer Science graduate from VIT. I mainly work with Java, Spring Boot, Angular, and React. I’m currently contributing to Apache Fineract, working on the Loan Origination System. Excited to learn, collaborate, and contribute with everyone here!
Hey everyone! I'm Mohith (github.com/mohithgowdak ) , a AI engineer based in Bengaluru, currently working at SAP Labs India. I spend most of my time around Python, FastAPI, and building agentic AI systems lately I've been deep in LangGraph, MCP servers, and RAG pipelines. What brought me here is wanting to sharpen my skills and connect with people building similar things. Fun fact: I have a coding alter ego named "Wintersoldie" that I switch into when I need to lock in for deep work sessions(kidding) Looking forward to learning from this group!
Hey everyone,
I'm a tech lead from germany, always trying to learn something new and share something with the world.
I am currently working in EdTech trying to support students in their struggles with the help of, who guessed it, AI. Originally a frontend dev, I now work in all fields relevant for web applications, and as a good jack of all trades, I am not exceptional at anything, I just know who to talk to.
I am going to share my learnings on the job, be it fundamental knowledge I gained over the years or just quick realisations from my current work day. And more importantly I am hoping to start discussions and learning from all of you.
Hi everyone.
I'm Kenneth, and from the Philippines.
A bit about me: I'm a full-stack developer with 8+ years of experience building web applications using React, Next.js, Node.js, and TypeScript. I work independently with clients globally.
I'm looking to connect with US-based developers for potential freelance collaborations.
If you're open to a brief 10-15 min virtual chat to exchange backgrounds, I'd be happy to share more details. If not, I completely understand and appreciate your time.
Best regards.
Hey! I'm Dhruv, a full-stack dev working mainly in MERN and Next.js/TypeScript. Just graduated with a CS degree and I've been building a couple of side projects lately, a real-time social app with Socket.io and a two-pass LLM pipeline for cold outreach using Groq. Been doing freelance LLM evaluation work on the side too, which has been a weirdly good way to see how models actually fail. Here to learn from people building real things and hopefully find some good discussions, not just lurking.
Hello everyone!
I'm John, a developer and builder who enjoys learning new technologies and turning ideas into real projects.
I joined DEV to learn from other developers, share experiences, and connect with people who are passionate about building things.
I'm currently exploring web development, APIs, backend architecture, and game development.
Looking forward to learning from the community and getting to know everyone.
What are you currently building or learning?
Hi everyone, I’m Rubén, based in Spain. I’m building Partle, an open catalog of products sold by physical hardware stores, with an API and an MCP server so AI assistants can search it.
Right now I’m facing the usual chicken-and-egg problem. I need users to make the site useful to sellers, but I also need sellers and their products to give users a reason to come.
My idea is to start by giving hardware shops free exposure through the catalog. If that helps bring in the first sellers, the users may follow. I’m here to learn from people who have built marketplaces or worked on practical AI and open data projects
Hi DEV 👋, I'm Althaf
I’m here because I’m passionate about building things with code and exploring how technology can solve real-world problems.
I’m especially interested in full-stack development, cybersecurity, automation, AI, and understanding how systems work from the inside out.
I’ll be sharing what I learn while building — projects, experiments, useful tools, security research, and ideas around creating smarter and more secure technology.
Always learning. Always building. Always breaking things to understand how they work.

¡Hola!
I’ve been working in IT for around 8 years and regularly interview with international companies. As a side project, I created a Telegram-based platform for technical interview preparation called ITInterviewCoach.
I’m currently working on growing it in both Spanish and English, and I’m still actively building and improving the project. Honestly, I’m really excited about it right now.
I’d like to keep that momentum going, and one of the best ways to do that is to connect with other developers, follow what they’re building, and exchange ideas and experiences.
Looking forward to meeting people here and learning from the community
Hi everyone! 👋
I’m Matsuken, a data scientist working on AI and machine learning at a Japanese technology company.
I recently joined DEV to share some of what I’ve learned and worked on in data science, machine learning, and AI.
I’ve just published a post explaining Q, K, and V in Transformer Self-Attention—one of the core mechanisms behind AI models like GPT that helps them determine which parts of the context are relevant—with a focus on intuition rather than just the equations.
Looking forward to learning from everyone here and sharing more posts. Nice to meet you all!
Hey everyone! I’m Nick. I enjoy building developer tools and experimenting with AI infrastructure. Currently working on VaultRun, a self-hosted runtime for AI agents. Looking forward to learning from other builders here.
Hey everyone, I'm Nikita! Excited to finally join the community.
My background is a bit of an unconventional mix, but here we are: a degree in Robotics & Mechatronics, diving into AI fundamentals since 2014, and moving through ML, cognitive science, and Big Data along the way.
My strong suits are mind mapping and cross-disciplinary thinking—connecting dots between different fields. And yes, not gonna lie, I definitely embrace the infamous 'vibe coding' approach. Python for complex, large-scale; C++ for fast, reliable. :)
Been meaning to jump into an active community of curious builders for a while now, and finally pulled the trigger. Happy to be here!
Hello,
I'm John
A medical student who is a tech and web enthusiast. I recently from last year started my coding journey and I'm really making progress.
I'm very interested in web development and I enjoy the works that web developers put on them.
I've strengthened my experience with HTML and CSS and just started my journey with JavaScript.
It will be tough but I hope I continue to enjoy and learn as I progress.

Hi all — Mihail, PHP/Laravel dev from Moldova.
Got here through one specific problem: scheduled jobs that stop running and tell nobody. No error, no log, everything green — until the day you need that backup. Ended up building a monitoring service around it, and now I mostly write about the failure modes I keep finding.
Here to read the #laravel and #devops tags. If you've ever found a dead cron job the hard way, I'd like to hear how.
Hey everyone, glad to be here. I'm a solo developer working on CloudCostTree, a CLI that helps you understand and experiment with what your AWS infrastructure will cost before you actually deploy it. Been heads down building it for the past few weeks and figured it was time to actually join the community instead of just lurking.
Been learning a lot about AWS's pricing internals along the way, turns out a lot of it is way more nuanced than it looks from the outside.
Looking forward to reading what everyone else here is building.
