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.

Product engineering

• ▲ Next.js · ⚛️ React · 🐱 NestJS · TypeScript
• ☁️ AWS (Certified Cloud Practitioner) · Terraform · Docker

AI engineering

• 🐍 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 like fixing the bugs I run into upstream instead of working around them. Some projects I've had changes merged into: bulletproof-react, react-native-paper, knip, typia, golevelup/nestjs, lektor.

• 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).

When I'm not coding, you'll probably find me:

• 🏋️ At the gym
• 🌿 Outside recharging
• 🎮 Gaming
• 🐱 Spending time with cats
