I will fix react next js and javascript bugs errors and issues fast


About this gig
Stuck on a React, Next.js or JavaScript error that just won't go away? I'll find the root cause and fix it fast without breaking the rest of your app.
I fix:
- React / Next.js errors, crashes & blank white screens
- JavaScript & TypeScript bugs
- Hooks, state, props & re-render issues
- API / fetch / CORS / async problems
- Build, deploy & Vercel errors
- Broken UI, responsive & CSS/Tailwind issues
What you get: a clear explanation of what was wrong, a clean fix (not a temporary patch), and working, tested code.
Fast replies, honest timelines, and I only mark the order complete when it actually works. Send me the error, a screenshot or your repo and I'll tell you what's wrong before you order.

FAQ
Can you fix it without breaking other things?
Yes — I find the root cause, not a quick patch, and test before delivering.
I only have one file, not the whole project — is that ok?
Yes, share whatever you have (file, repo link, or zip).
What if it turns out to be more than one bug?
Message me first with the details and I'll send a custom offer.
Which stacks do you cover?
React, Next.js, JavaScript, TypeScript, Node.js, Nest.js and common UI libraries (Tailwind, MUI).
Do you work on existing/large codebases?
Yes — I'm comfortable jumping into existing projects.
