Performance Profiler
PremiumPerformance problems rarely announce themselves — they creep in as the codebase grows until suddenly your app takes 4 seconds to load and your database is groaning. The challenge is knowing WHERE to look: is it the 2MB JavaScript bundle? The N+1 query that fires 200 SQL calls per page load? The React component that re-renders 60 times per second? Most teams guess and optimize the wrong thing. This skill performs a systematic multi-dimensional analysis: bundle size and tree-shaking opportunities, React rendering performance (unnecessary re-renders, missing memoization), SQL query patterns (N+1 detection), memory leak patterns (uncleaned listeners, growing caches), and algorithmic complexity hotspots. Each finding is prioritized by estimated impact so you fix the 20% of issues causing 80% of the slowdown.
