I will fix bugs errors in your react next js or node js app within 24 hours
Muhammad S
About this gig
Build failing? Page crashing? API returning 500? Deployment broken on Vercel? I find the root cause and fix it properly, not patch over it, usually within hours.
What I fix:
- React and Next.js: rendering errors, hydration issues, routing, state, hooks, build failures
- Node and Express: API errors, auth, CORS, database queries, memory leaks
- TypeScript errors, failing tests, broken CI
- Deployment: Vercel, Netlify, AWS, Docker, environment and config issues
- Integrations: Stripe, Supabase, Firebase, Prisma, MongoDB, Postgres, third-party APIs
How it works:
1. Send the error message, a screen recording, or a repo link
2. I confirm the scope and time before you order
3. You get the fix, a test to prove it, and a short explanation of what went wrong so it does not happen again
Full-stack developer, 8+ years, over 100k USD delivered on other platforms. I work in your repo with clean, minimal commits and never break what already works.
Message me the error first. Scoping is free and takes minutes.

FAQ
How fast can you actually start?
If I am online, within the hour. I confirm scope before you order so the 24-hour delivery is realistic. For emergencies, message me and I will send a custom offer.
Do you need access to my code?
Yes, read and write access to the repo (GitHub, GitLab, or Bitbucket) or a zip. For deployment issues I may also need Vercel or hosting access, which you can revoke afterward.
What if the bug is bigger than expected?
I scope before you order, so this is rare. If it happens, I stop, explain what I found, and offer a fair custom offer for the extra work. No surprises.
Do you fix bugs in WordPress, PHP, or Python apps?
This gig is for JavaScript and TypeScript stacks. For PHP, Python, or WordPress, message me first; I will tell you honestly if I can help.
Will you explain what caused the bug?
Always. Every delivery includes a plain-English note on the root cause and how to avoid it. If you want, I will also do a short Loom walkthrough.
