Muhammad N
About this gig
Built your app with Lovable, Bolt, Replit, v0, Base44, or another AI coding tool but stuck with bugs? I help founders fix AI-generated apps and make them stable for production.
I don't apply quick patches. I find the root cause, fix the issue properly, and improve code quality for long-term reliability.
I can help with:
Bug fixing & debugging
React & Next.js errors
Supabase authentication & database issues
API & backend problems
Deployment (Vercel, Railway)
Performance optimization
Code refactoring
AI-generated code cleanup
Tech Stack: React, Next.js, TypeScript, Node.js, Express, NestJS, MongoDB, PostgreSQL & Supabase.
Share your GitHub repo or ZIP file and a brief description of the issue. I'll review the project, confirm the scope, fix the bugs, test everything, and provide a summary of the changes.
Please contact me before placing an order for large or complex projects.

FAQ
Can you fix code generated by ChatGPT, Claude, Cursor or Gemini?
Yes. I work with AI-generated code regardless of which assistant or platform created it.
My app was built with Lovable / Bolt / Replit / v0 / Base44, can you still fix it?
Yes. These tools generate fairly similar output under the hood, usually React or Next.js on the frontend with Supabase, Firebase, or a similar backend. I don't need to have used the specific tool myself to read and fix the code it produces.
What if the bug is not fixed?
I offer free revision until the issue is fully resolved.
Is my code kept confidential?
Yes. I don't share, reuse, or disclose your codebase or business details.
What if my project has more bugs than my package covers?
Message me before or after ordering and I'll scope a custom offer for the extra work rather than leaving anything half-fixed.
Can you also deploy my app once it's fixed?
Yes, deployment (Vercel, Railway, etc.) is available as an add-on.
Do you only work with Next.js and Supabase?
Those come up most often since they're common in AI-generated apps, but I also work across the full MERN stack and NestJS. Message me first if you're unsure your stack fits.
How fast can you start?
I can usually review your repo and confirm scope within a hour of getting access, fix delivery follows your selected package's timeline.
