I will debug and fix your react nextjs website
Hamza Saddique
Over deze dienst
Need a react bug fix or a nextjs bug fix on a broken app? I debug and fix React and Next.js issues fast, from UI bugs and API errors to performance problems, hydration issues, and failed deploys.
I have 4+ years of development plus a QA testing background, so I find the root cause, not a patch that breaks again next week.
WHAT I FIX
- React and Next.js bugs and console errors
- API integration, auth, and session issues
- Responsive layout and CSS problems
- Slow page load and performance
- Build, Vercel, and Netlify errors
- Hydration, SSR, and javascript debug issues
HOW I WORK
1. You share the repo or ZIP plus error details
2. I diagnose and confirm the website bug fix
3. I fix, test, and explain what changed
I also fix NestJS and Django backend bugs when they affect the frontend. Simple react bug fix jobs often take 24 to 48 hours. Send the error, screenshot, or repo link. I reply within 1 hour with an estimate.

Veelgestelde vragen
How fast can you fix a React or Next.js bug?
Simple bugs: 24-48 hours. Complex issues such as auth, hydration, or deploy failures: 3-5 days after I confirm scope. Share the error and I will give an honest estimate before you order.
Do you need GitHub access for a website bug fix?
For most react bug fix and nextjs bug fix work, yes. I can also work from a ZIP for smaller tasks. I only change what is needed for the fix
What if you cannot fix the issue?
I tell you before starting if it is out of scope. You should not pay for a guess. If we agree it cannot be done in the package, we stop.
Do you fix backend bugs too, or only React?
I fix React and Next.js first. I also fix NestJS, Django, and REST API bugs when they cause the frontend error.
Will you explain what caused the bug?
Yes. Every delivery includes a short summary of the cause, the fix, and how to avoid it. That is part of the javascript debug process, not an extra.
Can you improve performance, not only fix errors?
Yes. Choose Standard or Premium for a performance check. Premium includes a written audit and a short walkthrough call.
Can you fix Next.js hydration and SSR errors?
Yes. Hydration mismatches, SSR crashes, and App Router issues are a common nextjs bug fix. Share the error log and I will confirm scope before you order.
Do you also handle javascript debug work outside React?
Yes. If vanilla JavaScript, TypeScript, or API client code is causing the website bug fix, I will trace it and patch the root cause.
