Performance Optimization

About

This skill equips Claude Code with a comprehensive toolkit for performing deep performance audits and optimizations across the entire software stack. It provides production-ready guidance for refactoring inefficient algorithms from O(n²) to O(n), resolving database N+1 query patterns, implementing advanced React memoization, and drastically reducing JavaScript bundle sizes. By integrating benchmarking frameworks and Lighthouse templates, it helps developers identify high CPU usage, fix memory leaks, and ensure applications consistently meet strict SLA targets and performance budgets.

Key Features

• Memory leak detection and allocation profiling
