I will fix bugs and errors in your react or next js app
Egon Warner
About this gig
Your app worked yesterday and now it doesn't. Maybe the build fails, a page shows a blank screen, or you're stuck on a hydration error that makes no sense.
I fix bugs in React and Next.js apps, and I tell you in plain English what broke and why, so it doesn't happen again.
What I can fix:
- Build and deploy errors (Vercel, Netlify, Docker)
- Hydration errors and pages that render blank
- Broken forms, API routes and data fetching
- TypeScript errors, dependency and upgrade problems
- Slow pages and performance issues
How it works:
- Send me the error message, a screenshot, or a short description
- I confirm I can fix it before you order
- You get the fix as a pull request or a ZIP, plus a short note explaining it
I'm a full-stack developer working in Next.js, React, TypeScript and Node every day. Before that I spent three years in technical support, so I'm good at turning "it's broken" into the actual cause.
Message me before ordering so I can look at your issue first.

FAQ
What if you can't fix it?
I look at the issue before you order and only accept work I'm confident I can fix. If something unexpected comes up, I'll tell you right away and we can cancel through Fiverr.
How do I give you access to my code?
The easiest way is to invite me to your GitHub repository. You can also send a ZIP of the project. I never need your passwords; you can remove my access when we're done.
Do you work with other frameworks?
My focus is React, Next.js, TypeScript and Node. I also work with ASP.NET Core APIs. For anything else, message me and I'll tell you honestly if I'm the right fit.
