Apprentice software developer @ Switch.

About

I'm Johan, a developer based in Zurich who likes building things end to end - from the interface someone touches to the AI and automation working behind it.

By day I'm an IT application developer in my apprenticeship at Switch, where I work on security tooling, internal platforms and a fair amount of Python automation. The rest of the time I build: experiments in scroll-driven 3D storytelling, and small tools that take repetitive work off people's plates.

I care about the same things in code that I care about in design - restraint, clarity, and making the complicated part feel effortless. I learn by shipping, and I'm most interested in where thoughtful interfaces meet capable AI.
