03How I work with AI
I use AI on every project. Every line still goes through tests, review and me.
- AI is a tool. Not an author, not accountable. I don’t act as a proxy for it — if I open the PR, I understand every line.
- I challenge the output instead of assuming it’s correct, and I review AI-written PRs with the same rigor as any other. The bar doesn’t drop because a tool helped.
- Speed is only valuable if it compounds. 4× with quality beats 5× with instability and rework.
