To fix unnecessary React re-renders, review your component structure and state handling to identify wasted work, then apply memoization and performance-aware refactoring to reduce redundant rendering cycles.

The best way to optimize Next.js data fetching is to apply Vercel-style best practices for caching, parallel fetching, and server components to eliminate waterfalls and reduce load times.

To reduce oversized bundles in React and Next.js apps, identify heavy imports and avoidable client-side work, then apply bundle splitting and code refactoring to minimize load-time overhead.

Yes, you can review existing React or Next.js codebases to identify performance issues like waterfalls, heavy imports, or avoidable client-side work, and receive specific refactoring suggestions to fix them.

You should apply server components and memoization during component development and page refactoring to correct rendering inefficiencies, optimize client and server behavior, and reduce load times in modern web applications.
