Hi, my name is

John Moorman.

I write software that pays for itself.

Software engineer in Berlin. I built an automation suite that saved a company €74K/year, letting two part-time administrators do the work of four. Now I ship AI-native software for clients, learning whatever stack the project needs and delivering on tight timelines.
