I will fix bugs in your react nextjs or nodejs web app
Farhan Shafi
About this gig
Have a React, Next.js or Node.js app that crashes, fails to deploy, or behaves differently in production? I will diagnose the real cause and fix it without unnecessary rewrites.
I have 6+ years of experience building and maintaining SaaS products, dashboards, and API-driven web applications.
I can help with:
- React rendering and state bugs
- Next.js routing, server action, and hydration issues
- Node.js and REST API errors
- Authentication, permissions, and database problems
- Failed builds and deployment issues
- Slow pages, broken integrations, and production-only bugs
Please send the error, reproduction steps, and repository context before ordering. I will confirm the correct package and flag anything outside the agreed scope.
You receive the repaired source code, a clear explanation of the cause, and 7 days of support.

FAQ
Can you inspect the repository before I order?

Yes. I regularly work in existing codebases and preserve the current architecture where practical.
Do you fix deployment issues?
Yes, including failed builds, environment configuration problems, and production-only errors.
Will you rewrite the whole app?
Not unless it is genuinely safer. I will explain the tradeoff before expanding the agreed scope.

Yes. You receive the updated source code with a concise summary of the cause and fix.
