Gig Summary

About this gig

So you (or an AI tool) vibe coded a mobile app and now it's crashing, slow, or impossible to build on. I fix that.

I specialize in taking AI-generated mobile code from Cursor, Bolt, Replit, Antigravity, or any "prompt and pray" workflow and turning it into clean, stable, production-ready apps. Native Android, native iOS, or hybrid (Flutter), I work across all of them.

What I fix:

  • Spaghetti architecture with no clear structure (MVVM, state management gone wrong)
  • Crashes and broken logic AI tools couldn't catch
  • Missing error handling and edge cases
  • Insecure data handling (exposed API keys, unsafe storage)
  • Performance issues (memory leaks, janky UI, slow builds)
  • Code that "runs" but can't scale, can't be maintained, or fails App Store/Play Store review

My process:

  1. Audit your codebase and flag critical issues
  2. Fix crashes and breaking bugs first
  3. Refactor into proper architecture (MVVM, clean separation of concerns)
  4. Hand back working, documented, maintainable code ready to ship

I build and ship production mobile apps daily: Android (Kotlin), iOS (SwiftUI), and hybrid using both traditional and AI-assisted workflows.

Send me your repo and I'll tell you honestly what shape it is.
