Optimization & Feedback
On tooling: I use modern development tools including AI-assisted coding to move faster and learn more efficiently. Every line of code I ship — whether written by me or with AI assistance — I understand, test, and can explain in a code review. The architecture decisions, tradeoffs, and system designs on this site are mine.
