Hi, I’m Raphael.
I’m a product engineer based in Brussels, Belgium. I’ve spent the last decade building iPhone, iPad and tvOS apps used by millions of people.
Right now I’m working on open source, agentic coding workflows and independent product ideas.
Current Work
I’m building tools I need for my own work, while using them to explore agentic coding workflows in practice.
