My name is Claudiu and I go by "ClaW". Yes, from the game.
I'm a Full Stack & AI Engineer based in Romania 🇷🇴, building products alongside fellow rebels at RebelDot. I spent years shipping web platforms end to end, and these days I also build the AI systems that sit inside them: agents, retrieval, evaluation, and the plumbing that makes them reliable.

- 🐍 Python · FastAPI
- 🤖 LLM agents with LangGraph and Claude
- 🔎 RAG with pgvector
- 📈 Observability and evals with Langfuse
I enjoy building scalable systems, clean APIs, and thoughtful user interfaces. I care about code clarity, structure, and long-term maintainability, and with AI features I also care about measuring what the model actually does.

- I'm passionate about continuous learning.
- I enjoy solving complex problems and thinking critically about trade-offs.
- I like understanding why something works, not just making it work. That goes double for LLMs.
- I care about writing structured, observable systems (yes, I like clean logs 😄, and clean traces).
I like contributing to open source in my free time, fixing the bugs I run into upstream instead of working around them. If you maintain a project and need a hand with something, feel free to ping me.
When I'm not coding, you'll probably find me:
- 🏋️ At the gym
- 🌿 Outside recharging
- 🎮 Gaming
- 🐱 Spending time with cats
