How I Work

I run development through an orchestrated team of AI coding agents, and I review every change before it reaches main.

  1. Parallel worktrees

    Agents work in separate git worktrees at the same time, so features move forward in parallel without stepping on each other.

  2. Staging-first releases

    Every change ships to a staging environment first and reaches production only after it has been checked there.

  3. Human review on every merge

    Nothing merges to main without my review. Agents propose, I decide.
