Luiz Fernando C. Castilho • Aug 5

Hi everyone!
I'm Luiz, from Brazil. I'm switching careers into tech after a background in Biotechnology and a Master's in Chemical Biology, where I spent years analyzing experimental data and documenting complex processes with a lot of rigor.

I'm currently studying Systems Analysis and Development, learning Python, APIs, and databases, and I'm genuinely excited about applying AI tools to real development workflows (I've been using Claude Code to automate parts of my own job search, actually).

Looking forward to learning from this community and sharing what I build along the way. Happy to connect with anyone else who's also transitioning into dev from a different field!

Oleksandr | CalculatorAI • Aug 5

Hey Luiz — I came into dev from marketing, so I know that jump well. The
"documenting things with rigor" habit helps way more than people expect.

Curious what you automated in the job search with Claude Code?

Pragathi Jayaram • Aug 5

Hey, I’m Pragathi, an applied AI systems consultant and founder building Anovi. I’m here to learn from other devs, share practical lessons from building and shipping real products, and connect with people working across AI, mobile, and backend engineering. Happy to join the community!

Miko Builds • Aug 5

Hey everyone! I'm Mikhail 👋
I'm an indie developer and software engineer building CLI tools and practical workflows around AI coding agents (mostly deep-diving into Claude Code, context engineering, and repository security right now).
I joined DEV to share real-world lessons learned from taming multi-agent coding pipelines and to connect with other builders who are figuring out how to stop LLMs from over-engineering or burning token budgets.
Excited to be here and learn from you all!

ARMAN AVASTHI • Aug 5

Hey all, Arman here, Applied AI and Java backend engineer in Oracle's AI pioneers team. Joined this dev community to learn and share latest technical stuff. I'd love to see how other folks are approaching the probelms in this era of AI and would love to share my insights as well.
Good to be here. Say hi if you're into distributed systems, agentic AI or just enjoy a solid production war story👋🏻

Ryan Baker • Aug 5

Hi, I'm Ryan. I've worked in software for 30 years, split between development and architect type work. I've been writing about AI safety, security and economics on my Substack for about a year now. Heard about this and thought this would be a good place to extend that conversation. I expect I'll cross-post here when I've got something I think is of interest.

Sahand Farshian • Aug 5

Hey everyone!
Glad to be here.
I'm a backend developer who enjoys building things with Java and Spring Boot, but lately I've been diving deeper into mathematical optimization and how it connects with software engineering.

I'm especially interested in the space where AI, optimization, and backend systems meet.
Figuring out not just how to predict things, but how to make better decisions.

Excited to learn from this community, share some ideas, and meet other developers along the way.

Happy Coding!

Datta sai krishna Naidu • Aug 5

Hi DEV 👋 I'm Datta, an AI/ML engineer in Los Angeles.

Day job is production RAG — retrieval pipelines, MLOps, private LLM deployments inside locked-down cloud environments for regulated clients. The part I actually care about is retrieval, because that's where most RAG systems quietly fail and nobody notices until a user asks something two hops deep.

That's what got me building hubmesh: a GraphRAG retrieval planner that drops in on top of whatever vector DB you already have — Qdrant, Chroma, in-memory. The premise is that questions like "where was the founder of the company that acquired Slack born?" don't fail because the model is weak. They fail because top-k cosine never retrieves the middle of the reasoning chain. So hubmesh runs a small Personalized PageRank over an entity graph at query time instead of just ranking by similarity. No LLM in the query path, which keeps it around 22ms per query on a 7K-node graph.

I'm also building aegis — an open-source iOS messenger using NIST post-quantum crypto by default, with a sandboxed lab for poking at novel algorithms. Very different problem, same instinct: I want to see the thing actually work end to end rather than read about it.

Here to write up what I learn from both. If you've shipped GraphRAG in production and it didn't beat plain hybrid search, I'd genuinely like to hear that — negative results are harder to find than the success posts and more useful to me.

Patrick Jerominek • Aug 5

Hi everyone, Patrick here from Frankfurt, Germany.

I work at xhub.io, where we build custom software plus a few products of our own. Most of my time goes into invoice-api.xhub — an API for European e-invoicing: XRechnung, ZUGFeRD, Peppol. It's a domain nobody picks voluntarily. An EU semantic standard, national formats that all differ just enough to hurt, and a legal deadline pushing everyone at once. Turning that into something you can call in a few lines of code is the actual product.

We also build mobile apps and test them with Maestro, so I'll be lurking in #testing and #mobile a fair bit.

Good to be here 👋

Kbir Singh • Aug 5

Hi! I'm Kabir building Testimonial Alchemist, a tool that turns customer testimonials into case studies, sales slides and social assets automatically currently in research mode talking to B2B marketing teams to understand how they handle testimonials after collecting them would love to connect with anyone here who works in SaaS marketing.

Nadia Baig • Aug 5

Hi, Nadia here. A bioinformatician by profession. Here to explore hot topics in bioinformatics software development, general computational biology topics and the latest trends in AI/ML for Biological data science. I love to write about the various topics related to Bioinformatics/ computational biology and you can see that in my profile :)

Oleksandr | CalculatorAI • Aug 5

I'm Oleksandr — a solo founder building CalculatorAI: calculators, trackers and
document generators under one account, with an AI layer across them. About a
year in, everything designed, built and shipped by one person.

Came from marketing, so I learned to code because I wanted to ship the thing
rather than brief someone else to. Here mostly for Next.js performance, SEO at
scale, and the surprising ways a hosting bill grows.

Happy to be around!
