performance-optimization
jankneumann
Optimizes application performance with the MEASURE → IDENTIFY → FIX → VERIFY → GUARD workflow. Covers frontend Core Web Vitals (LCP ≤ 2.5s, INP ≤ 200ms, CLS ≤ 0.1), bundle budgets, and React re-render hygiene, PLUS backend latency budgets, Postgres/MySQL EXPLAIN ANALYZE workflows, N+1 query detection, connection-pool sizing, and async profiling with py-spy / cProfile. Use when performance requirements exist, when Core Web Vitals or p95 latency miss thresholds, or when profiling reveals bottlenecks that need fixing.
