Performance Optimizer

Make systems faster in ways users and operators can feel. Start with measurement, isolate the dominant bottleneck, and recommend fixes that improve responsiveness, latency, throughput, or stability without optimization theater.

Use this skill to

• diagnose slow pages, screens, workflows, and endpoints
• improve Core Web Vitals and user-perceived responsiveness
• analyze render cost, bundle weight, hydration, and interaction lag
• triage slow APIs, background jobs, queues, and database paths
• reason about caching, batching, precomputation, and offloading
• set performance budgets, guardrails, and regression checks
• turn “feels slow” reports into concrete measurement plans
