I will debug and fix errors in your javascript react nextjs code
Md Yousuf
About this gig
Got a bug in your React or Next.js app that's driving you crazy? I'll find it and fix it fast.
I'm a full-stack developer with hands-on experience in Next.js, React, TypeScript, and Node.js. Whether it's a broken component, a state management issue, an API that's throwing errors, a styling glitch, or something that just "isn't working right" send it over and I'll take a look.
What I can fix:
- Console errors and warnings
- Broken UI components or layout issues
- API/data fetching problems
- Authentication and routing bugs
- Build/deployment errors
- Performance issues
Send me your error message, a screen recording, or repo access and I'll diagnose it before starting no guesswork, no wasted revisions.
Need something bigger built from scratch instead? Check out my other gig for full application development.

FAQ
Do I need to share my full codebase?
No — just the specific file(s), a GitHub repo link, or a code snippet where the issue is happening. If it's easier, screen share or send repo access and I'll only touch what's needed to fix the bug.
What if the bug turns out to be bigger than expected once you look at it?
I'll message you before doing any extra work and explain what I found. We can then agree on an upgrade to Standard/Premium if needed — no surprise charges.
Do you fix bugs in frameworks other than React/Next.js?
My core focus is React, Next.js, JavaScript, and TypeScript. If you're using something else, message me first and I'll let you know honestly if it's a good fit.
