I will fix bugs and errors in your react or next js website fast
Kabir Sheikh
About this gig
Is your React or Next.js app throwing errors, broken layouts,
or not working as expected? I will fix it fast and cleanly.
I have hands-on experience building full stack applications
with React.js, Next.js, Node.js, Tailwind CSS, and REST APIs.
I do not just patch the symptom I find the root cause and
fix it properly so it does not come back.
I can fix:
- Console errors and runtime crashes
- Broken components and UI layout issues
- API calls not working or returning wrong data
- Authentication and JWT token problems
- State management bugs in React hooks
- Next.js routing and page rendering issues
- Tailwind CSS styling and responsiveness problems
- Form validation and submission errors
- CORS errors and backend connection issues
- Performance issues and slow loading
How it works:
- Share your code or GitHub repo with me
- I identify the exact root cause
- I fix it cleanly and push the solution
- You receive working code with a full explanation
I respond within 1 hour and always deliver before the deadlin

FAQ
What do I need to share with you?
Share your code via GitHub repo, zip file, or paste the relevant snippets. Describe the bug and what you expected to happen. The more detail you give, the faster I fix it.
What if you cannot fix my bug?
I will tell you honestly before you order if the issue is outside my scope. If I accept and cannot fix it, I will give you a full refund with no questions asked.
Do you work with TypeScript?
Yes, I work with both JavaScript and TypeScript in React and Next.js projects.
Can you fix bugs in my backend too?
If your backend is Node.js or Express, yes. For other backends message me first and I will let you know.
Will you explain what was wrong?
Always. Every delivery includes a clear explanation of what the bug was and exactly how I fixed it. You will understand your own code better after.
