What problem does it solve?
Diagnoses and fixes front-end performance problems that cause slow loading, janky rendering, long input delays, and excessive bundle size to create faster, smoother user experiences.
Core Features & Use Cases
- Performance Assessment: Measure Core Web Vitals (LCP, FID/INP, CLS), Time to Interactive, FCP, TTI, and runtime CPU/memory usage to identify bottlenecks.
- Loading & Network Optimization: Reduce bundle size via code splitting and tree shaking, optimize images with modern formats and responsive loading, and apply caching and CDN strategies to lower payloads and request counts.
- Rendering & Animation Improvements: Eliminate layout thrashing, use GPU-accelerated transforms and requestAnimationFrame, employ content-visibility and virtualization for long lists, and tune CSS and font loading to reduce paint and composite costs.
- Framework Guidance: Practical React and framework-agnostic recommendations such as memoization, lazy loading, web workers for heavy tasks, and profiling with DevTools and bundle analyzers.
- Monitoring & Validation: Use Lighthouse, WebPageTest, Core Web Vitals, and real-device testing to measure before-and-after impact and avoid regressions.
Quick Start
Run an audit with Lighthouse and prioritize fixes for LCP, JS bundle reduction, and image optimization, then measure improvements on a throttled mobile profile.
