About
I'm Johan, a developer in Zurich who builds things end to end - from the interface someone touches to the AI and automation working behind it.
I work on security tooling, internal platforms and Python automation at Switch, and build my own products on the side - scroll-driven 3D experiences, AI workflows on the Claude API, 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 ship fast, and I'm most interested in where thoughtful interfaces meet capable AI.
