AI Engineer · BSc ICT & AI

Eindhoven, NL

I build LLM and agent systems — and care most about proving their output can be trusted. My route into AI wasn't a straight line: a Python bootcamp in Sofia, then network engineering at IBM, then a move to the Netherlands to study AI at Fontys. Since then I've shipped production AI features for a health-tech platform, built internal AI tools with researchers at the University of Birmingham, and trained computer-vision models for logistics. The question I keep coming back to: how do you actually know an agent is right?
