I'm Johan, a software engineer apprentice based in Zurich. I build interfaces, AI workflows and tools that take repetitive work off people's plates.

At Switch

I currently work in Registry (Domain Applications), after rotations in video, security, and trust & identity.

On my own time

I explore creative web experiences, Claude-powered workflows and small tools that make daily life easier.
