Performance
40% faster
Speed is the first thing users feel. On a platform with 50,000+ active users, making pages 40% faster was noticeable to everyone.
Measure first
Guessing where time goes is usually wrong. Profiling showed which bundles, requests, and renders actually slowed pages down.
Ship less, earlier
Splitting code, loading data closer to where it's used, and caching what doesn't change delivered most of the gains.
