I will fix nextjs react bug
Muhammad Alyan
About this gig
Is your Next.js website throwing errors, crashing, or not behaving as expected? I can help.
I specialize in identifying and fixing bugs in Next.js applications from broken pages and failed builds to API errors, hydration mismatches, and routing issues. Whether it's a small glitch or a critical bug blocking your launch, I'll dig into your codebase, find the root cause, and deliver a clean fix.
What I can fix:
- Build & deployment errors (Vercel, Netlify, custom servers)
- Hydration errors and SSR/CSR mismatches
- Broken routing (App Router & Pages Router)
- API route failures and server errors
- Styling and layout bugs (CSS, Tailwind, responsive issues)
- Performance issues (slow page loads, unoptimized images/data fetching)
- Third-party integration issues (Stripe, Auth, databases, CMS)
- Console errors and warnings
Why work with me:
- Clear communication throughout
- Clean, well-documented fixes (no messy patches)
- Fast turnaround
- I explain what caused the bug and how I fixed it
Send me your error message, repo, or a description of the issue, and I'll get back to you with a quick assessment before we start.

FAQ
Do I need to share my full codebase/repository?
Yes, typically I'll need access to your GitHub/GitLab repo (or a zip file) along with a description of the issue so I can reproduce and diagnose it properly.
What information should I provide when placing an order?
Please share: a description of the bug, any error messages or screenshots, steps to reproduce the issue, and access to your repository (or relevant code files) and live site if available.
How do I share access to my project?
You can invite me as a collaborator on GitHub/GitLab, or send a zip file of the project through Fiverr's file-sharing feature. I'll always ask for exactly what I need to get started.
What Next.js versions do you work with?
I work with both the App Router and Pages Router, and support recent Next.js versions (12 through 15). Let me know your version if you're using an older one, since some fixes differ.
How long will it take to fix my bug?
It depends on the complexity of the issue. Simple bugs are usually fixed within 24–48 hours. More complex issues (deep architecture problems, multiple interconnected bugs) may take longer — I'll give you a clear timeline after reviewing the issue.
What if the bug isn't fully described or I'm not sure what's causing it?
No problem — send me whatever details you have (error logs, screenshots, unexpected behavior) and I'll investigate to find the root cause before starting the fix.
