About this gig
I will fix react and next js bugs errors and performance issues
Is your React or Next.js app broken, slow, or throwing errors you can't track down? I'll find the root cause and fix it, usually within 24-48 hours.
I'm a web developer with 10+ years of experience building production websites and apps with React, Next.js, TypeScript and WordPress.
What I can fix
- Build errors and deployment failures (Vercel, Netlify, VPS)
- Hydration errors and SSR / SSG / ISR issues
- API routes, data fetching and routing bugs
- State management problems (Redux, Zustand, Context)
- Slow pages: Core Web Vitals, bundle size, image optimization
- Broken layouts and responsive issues (Tailwind, CSS)
- Upgrades: Next.js pages router to app router, React version updates
How it works
1. Send me a message with the problem and a link to your repo or site.
2. I review it and confirm the price and timeline.
3. I fix the issue in a separate branch, so your main code stays safe.
4. You get the working code and a short explanation of what was wrong.

FAQ
What do you need from me to start?
Access to your code repository (GitHub, GitLab or a zip file), a description of the problem, and steps to reproduce it. If it's a live issue, a link to the site and any error messages or screenshots help a lot.
Do you work with TypeScript and Tailwind?
Yes. I work with React, Next.js (pages and app router), TypeScript, Tailwind CSS, and common libraries like Redux, Zustand, React Query and Prisma. If your stack is different, message me and I'll tell you if it fits.
What if you can't fix the problem?
Message me before ordering with a short description. I'll tell you honestly if I can solve it. If I start working and find I can't fix it, I'll let you know right away and you won't pay for the unresolved part.
