Analyzes and optimizes performance across frontend, backend, and database layers: CPU, memory, I/O, bundle size, queries, images, and rendering.
Diagnoses frontend and backend performance bottlenecks including bundle size, N+1 queries, memory leaks, and Core Web Vitals. Prioritizes fixes by impact.
