About

I'm Johan, a Zurich-based developer building at the intersection of product interfaces, automation and AI.

At Switch I work on security tooling, internal platforms and Python automation. On the side I build creative web experiences, Claude-powered workflows and small tools that take repetitive work off people's plates.

I care about clear interfaces, restrained design and systems that make complex work feel effortless. I ship fast, and I'm most interested in where thoughtful interfaces meet capable AI.
