Picture of Jeroen Herczeg

Hello, I'm Jeroen Herczeg.

I'm a senior software engineer building AI systems for production.

I have 20 years of engineering experience across software platforms, distributed systems, and product teams. Today, my work focuses on retrieval-augmented generation, AI agent orchestration, and practical AI engineering.

Most recently, I contributed agents and orchestration work to the Google + BBC AI Agents demo at IBC2025, winner of the Broadcast Tech Innovation Award.

I wrote Retrieval-Augmented Generation: An Engineer's Guide to Building RAG Systems with Your Own Data. It's out now on Leanpub.

Based in Belgium. Working globally.
