01 About

I'm a software developer who likes the whole stack to be understandable by one person. On the server that means Go: a single static binary, the standard library wherever it will do, and boring, observable deployments.

On the client it means Flutter: one codebase that ships to iOS and Android with native feel, offline-first data, and attention to the small details that make an app pleasant to live with.

I ship my own products as well as working for others, which keeps me honest about what matters: things that are simple, reliable and respectful of the people using them.
