I will fix next js bugs, react errors and vercel deployment issues


About this gig
Your Next.js site is broken, your build keeps failing, or your Vercel deployment won't go live? I'll find the cause and fix it, usually within 24 hours.
What I fix:
- Hydration errors and "window is not defined" issues
- Build and deployment failures on Vercel, Netlify or Firebase Hosting
- API route, server component and data-fetching bugs
- TypeScript errors and broken imports
- Slow pages (images, bundle size, Core Web Vitals)
- Responsive layout and Tailwind CSS bugs
- State issues with Redux Toolkit or Context
How it works:
1. Send me your repo link or code and the error message.
2. I reproduce the problem and tell you the cause.
3. I fix it, test it, and explain what changed so it doesn't come back.
I work with React, Next.js, TypeScript, Firebase and FastAPI backends, and I write clean code you can maintain.
Not sure if your issue fits? Message me before ordering and I'll tell you honestly whether I can fix it and how long it will take.

FAQ
Do you need access to my code?
Yes, a GitHub invite or zip file. I only touch what’s needed for the fix.
What if you can’t fix it?
I’ll tell you before starting if it’s out of scope, and I’ll cancel rather than waste your money.
Will you explain the fix?
Yes, every order includes a short written explanation.
Do you work with Vite, Create React App or Remix?
Message me your setup and I’ll confirm.
