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.
I'm an engineer at Wemogy and study Computing & IT at the Open University. Before software I spent six years in emergency services, which is where I learned that the interesting part of a system is how it behaves at 3am.
Client work runs through my company, Gietmanic.
