I will fix bugs in your react, next js or node js app fast


About this gig
Something broken and you need it working today?
I'm a senior full-stack developer and CTO. I've spent years fixing production issues in React, Next.js and Node.js apps: the kind where the stack trace lies and the real cause is three layers down.
WHAT I FIX
Hydration errors, build failures, "works locally, breaks in prod"
Broken state, infinite re-renders, stale data, useEffect loops
API and CORS errors, auth and session problems
Type errors, dependency conflicts, failing Vercel deploys
HOW IT WORKS
You send me the repo and describe what's wrong. I find the root cause, fix it, and explain in plain English what was happening, so it doesn't come back.
You get working code, a short explanation, and no lectures about your codebase.
Message me with the error before ordering. I'll tell you honestly if I can fix it and which package you need. If I can't help, I'll say so.

FAQ
Do you need access to my repository?
Yes, a GitHub or GitLab invite, or a zip file. I'm happy to sign an NDA before you send anything.
What if the bug turns out to be bigger than expected?
I tell you before I start and we agree on a package that fits. I never begin work you haven't approved, and I won't quietly run up the scope.
Which React and Next.js versions do you work with?
All modern versions, both the Pages Router and the App Router, JavaScript or TypeScript. Same for Node.js, Express, NestJS and Fastify on the backend.
Can you also add a feature, not just fix a bug?
Yes. Message me with what you need and I'll send a custom offer with a fixed price and a realistic deadline.
