Building software, and writing about the road between.
I'm a software engineer working on distributed systems and developer tooling. This is where I keep my notes on technology, the places I've been, and the things I've built. No newsletter pop-ups, no cookie banner — just writing.

Selected work
All projects →Project Alpha

Project Beta
Self-hosted uptime monitoring that fits in 40MB of RAM. Built because everything else wanted a database cluster.
