Clean PRs, thoughtful reviews, zero drama. He became the person the whole team turned to when something felt off architecturally. He elevated everyone around him.
We needed someone to own the Angular architecture from day one. He scoped the whole thing, pushed back on scope creep at the right moments, and delivered on time.
