Over mij
AI is at the heart of what I build. I create AI agents, RAG chatbots and LLM apps (OpenAI, Gemini, LangChain) that let businesses chat with their own data, plus the web apps, custom software and SaaS backends around them.
A major bank and multinational FMCG brands trust my code in production. I ship fast using modern AI coding tools.
Stack: Java Spring Boot, Python FastAPI, Node, React, Next.js, Postgres, Qdrant, Docker, AWS.
5.0 rated, 1-hour response. Tell me your idea and I'll turn it into a clear plan, price and timeline.
