About this gig
Did you build a web app or mobile app with Replit, Lovable, Bolt, Cursor, v0, Base44, or another AI/vibe coding tool, but now you are stuck with bugs, errors, broken features, database issues, auth problems, or deployment problems?
I will help fix, debug, improve, or finish your vibe coded web app and prepare it for real use.
I can help with:
- Bug fixing and debugging
- Replit, Lovable, Bolt, Cursor, v0, and Base44 projects
- AI generated web app cleanup
- Frontend and backend fixes
- Supabase, Firebase, API, and database issues
- Authentication and login problems
- Broken forms, buttons, pages, and workflows
- Deployment and production setup
- Performance, security, and code structure improvements
- Preparing your app for launch
Many AI generated apps look good at first, but fail when real users, data, payments, auth, or deployment are involved. I can review your project, identify the issues, and help turn it into a more stable and usable web app.
Please contact me before ordering so I can review your app, check the current state, and recommend the right package.
