React
and Next.js
speed optimization.
I optimize React and Next.js frontends: reduce bundle size, configure code splitting and lazy loading, eliminate unnecessary re-renders, and enable SSR / SSG for fast first paint.
React frontends are slow most often because of excess JavaScript: a massive bundle, unnecessary re-renders, and heavy components loaded on startup. I find these issues through measurement, split and lighten the code, and where needed — enable Next.js server-side rendering.
What's included in frontend speed optimization
Bundle size
JS analysis and reduction: removing heavy dependencies, tree-shaking, and import optimization.
Code splitting
Code splitting and lazy loading — users only load what's needed for the current screen.
Rendering
Eliminating unnecessary re-renders, memoizing heavy components, and optimizing state management.
SSR / SSG
Server-side rendering and static generation in Next.js for fast first paint and SEO.
