Half my projects start with “this is annoying.” The other half start with “what if?”
I'm Jurgen, a product engineer based in Europe with six years of experience. I work with teams across Europe and the US in React, Next.js, Angular and Node.js, taking technical ownership of frontend architecture, migrations and mobile releases. Outside that, I build iOS apps, release tools, local-first software and AI experiments.
I like clean interfaces, fast feedback, and code that holds up when someone uses it in a way I didn't expect. Getting it working is the start. Getting it right is the fun part.
