How I build with AI
AI-driven development, with a human in the loop.
-
Turn the problem into a clear spec: goals, constraints and the checks that prove it works.
-
Break the work into small steps and settle the architecture before any code is written.
-
AI agents draft the code and tests inside the repo, one step at a time, with context from the spec.
-
I read every diff and run Playwright, Lighthouse and evals, then fix what the AI got wrong.
-
CI/CD to production, then measure and feed what I learn into the next brief.
