Skills for performance work: profiling, finding bottlenecks, cutting bundle size and request waterfalls, and measuring results.
Turns speed-up requests into a bounded, measured loop: baseline first, one-hypothesis variants, a correctness gate, and the fastest safe variant wins.
Measures live page metrics from performance.getEntries() in a browser and compares them with a saved baseline to detect web performance regressions.
Optimizes frontend, backend and database performance via a measure, identify, fix, verify and guard loop, keeping only changes that measure better.
Sets bundle-size and Lighthouse thresholds in CI and fails builds over budget, so regressions surface at PR time.
Diagnoses why web animations drop frames and keeps them within the frame budget using composite-only properties and off-main-thread motion.
Profiles Python code with cProfile, line_profiler, memory_profiler and py-spy, then optimizes bottlenecks using documented performance patterns.
