Multi-country intercity bus booking platform with Adyen payments across Europe.
Senior Full Stack and AI Engineer with 15+ years of software engineering experience and hands-on production LLM work since 2024. I design, ship, and operate LLM systems end to end: multi-agent pipelines with LangGraph (supervisor/worker patterns), RAG with hybrid retrieval, and the part most teams skip: evaluation and observability with LangSmith, Ragas, and calibrated LLM-as-a-Judge. Strong full stack background (TypeScript, React, Node.js, Python) for taking AI features from prototype to production.
