The build log · Production agentic engineering
AI agents ship our code. I show you how.
I'm Bernhard Keprt, cofounder and CTO of appointmed, a profitable healthcare SaaS where 100% of production code is written through AI agents. This is the build log.
Every two weeks: what we shipped with agents, what broke, and what the work taught us inside a real production codebase.
