About
I build software for humans and AI agents.
I'm Dennis, a software engineer and solopreneur. Most of my work sits somewhere between product engineering, AI interfaces, and the developer tooling that makes teams move faster without losing the plot.
I am a father of 3, originally from Berlin, Germany, and now living in Oslo, Norway.
