Hi, I’m Stefan.

I’m a full stack software developer from Hamburg with a soft spot for the frontend. I care about doing things properly - clean, solid code, but also about the product it ends up in - in the end it’s about building things people actually like to use.

When I’m not coding, I’m probably doing sport, enjoy nature, playing computer games, or - every now and then - dj or taking photos.
