React & Next.js Bug Fix & Performance Optimization
Fix bugs, improve speed, and make your React or Next.js application perform better.
I troubleshoot and optimize React and Next.js websites and web applications, identifying technical issues that affect functionality, loading speed, stability, SEO, and user experience.
What I Fix & Optimize
Area Examples Bug Fixing UI bugs, broken features, runtime & console errors Performance Slow pages, rendering issues & excessive loading Core Web Vitals LCP, INP, CLS & page experience React / Next.js Rendering, hydration & component issues JavaScript Memory, execution & unnecessary re-renders API Performance Slow requests, inefficient data fetching & caching Bundle Optimization Large bundles, unused code & heavy dependencies SEO Performance Technical issues affecting crawling & page speed
Optimization Services
✓ Code Optimization — Cleaner and more efficient React/Next.js code
✓ Rendering Optimization — Improve SSR, SSG, ISR & client rendering
✓ Image Optimization — Reduce image size and improve loading
✓ Bundle Optimization — Reduce JavaScript and unnecessary dependencies
✓ Caching — Improve data and page delivery
✓ API Optimization — Reduce unnecessary requests and response times
✓ Database/API Analysis — Identify backend bottlenecks affecting the frontend
✓ Core Web Vitals — Improve real-world page performance
Technology Stack
React.js • Next.js • TypeScript • JavaScript • Node.js • REST APIs • PostgreSQL • Redis • Vercel • Docker
Process
Audit → Identify Issues → Fix → Optimize → Test → Measure → Deploy
I focus on measurable improvements, stable functionality, clean code, faster loading, and a better user experience rather than applying generic optimization techniques.
Is Your React or Next.js App Slow or Buggy?
Share your application, error, performance issue, or Lighthouse/Core Web Vitals report — I'll investigate the root cause and work toward a reliable solution.
