I build software and keep it running.
Mostly TypeScript, Go and Swift. Some of it ships to the App Store, most of it ends up on GitHub, and a fair amount runs quietly in the background of other people's businesses.
Before software I spent six years in emergency medical services and dispatch. That is where I learned that the interesting part of a system is how it behaves at 3 a.m.
