About this gig
Is your React or Next.js application slow, unstable or difficult to maintain? I diagnose and fix the real cause.
I can help with:
React and Next.js runtime or build errors
Core Web Vitals, bundle size and loading performance
Unnecessary renders, memory leaks and state issues
API integration, authentication and data-fetching bugs
Responsive UI and cross-browser problems
TypeScript, Redux, MobX and component architecture
Next.js upgrades, deployment and production failures
You receive a clear diagnosis, focused code changes, testing and a summary of what was fixed. I have 7+ years of production experience across SaaS, telephony, fintech, logistics, IoT and marketplace applications.
Please message me with the issue, repository details and expected behavior before ordering so I can confirm the correct package.
