Overseer
Featured · 2026An orchestration system for AI coding agents. It turns a feature request into small tasks and takes each one from prompt to reviewed, merged code. In 17 days it ran 3,322 agent sessions and landed 741 tasks.
- —Each task runs with its own agent (Claude, Codex or OpenCode) in an isolated git worktree.
- —A second model reviews every change; it is verified against a definition of done before merging.
- —Tracks cost per task and feeds lessons from its mistakes back into its prompts.
- —A live pixel-art “office” shows the agents at work.

I'm a software developer in the Amsterdam area with eight years of experience building for the web. Most of my work is in Vue, TypeScript and React.
Lately I design workflows in which AI agents write production code: work is split into small tasks, every change is reviewed and verified, and a person approves the merge. Overseer came out of that work.
I like work I can check. I write the tests before the code, keep each change small, and don't call something done until there's proof: a green run, a screenshot at every breakpoint or a measured number. I work best in a cross-functional team where things get said plainly, in Dutch or English. When something breaks, I don't stop at the fix: I find out why it happened and turn that into a test, a check or a rule, so the same mistake doesn't come back, for the team or for the AI agents I work with.
