Engineering Lead / Tech Lead for Generative AI and AI agents. Python, Node.js, AWS. Based between Brussels (Belgium) and Spain.

Building production systems since 2012, focused on GenAI since 2023: AI agents and LLM tools that business teams use every day. I work embedded with the business, from use-case workshop to production MVP, and leave teams able to maintain what we built.

• ReArch — self-hosted background AI coding agents for whole teams: each person gets an agent in a sandboxed container working on the team's real repositories, with a pull request at the end.
• Ronsel (source) — open-source end-to-end test framework where each test is a Markdown notebook you read like docs and run against real APIs, databases, MQTT and browsers.
• LLM proxy — open-source gateway that secures and controls LLM usage across an organisation: what data leaves, who uses which model, at what cost.
• redact — detects sensitive data in repositories before it reaches an LLM.
