I will turn your ai coded prototype into a production app

About this gig
Your vibe-coded app looked finished in the demo. Then a real user hit it, or you asked for one more feature, and it started breaking in ways ChatGPT can't explain.
I'm a fullstack and native mobile developer, 8 years in. Most of my work now is inside code built with Lovable, Bolt, Replit, Cursor, v0, or plain ChatGPT. The pattern repeats: auth that isn't enforced server-side, database calls with no indexes or limits, API keys sitting in the frontend bundle, errors that get swallowed instead of handled.
What you get:
- Full code audit: what's broken, what's a security risk, what's salvageable
- Bug fixes & refactoring: web (React, Next.js, Node) and native mobile (Swift, Kotlin, React Native, Flutter)
- Security pass: auth, API keys, input validation, rate limits
- Performance fixes: slow queries, re-render loops, bloated bundles
- Getting a stalled build actually deployed and stable
I read your code before I quote. Send the repo or the Lovable/Bolt/Replit link. I'll tell you straight what's fixable, what needs a partial rebuild, and what it costs. No charge for that first look.

Most weeks start with a Lovable link, a Bolt export, or a repo where the last commit says "it worked yesterday." Eight years as a fullstack and native mobile developer. The last two were spent mostly repairing what AI tools get right on the surface and wrong underneath: auth that isn't checked server-side, queries that die past a few hundred rows, errors that get swallowed instead of handled. I build in React/Next.js, Node, native iOS (Swift), native Android (Kotlin), React Native, and Flutter. I read your code before quoting, so you know what's actually broken first.
FAQ
My app was built with Lovable, Bolt, Replit, or Cursor. Can you actually work with that?
Yes. You don't need to explain the tool or the stack. I'll read the code and tell you what's actually there in the first look.
What if my project needs a rebuild instead of a fix?
I'll tell you before you order. Sometimes patching costs more than rebuilding the backend while keeping your UI. I'll lay out both options and the real cost difference.
Do you need admin or hosting access?
For anything beyond a read-only review, yes — repo access at minimum, hosting or database access for deployment work. I'll send a short access checklist after you order.
I'm not technical. Will I understand what's wrong?
Yes. You'll get a plain-language summary alongside the technical one. You don't need to know what a race condition is for me to explain why your app double-charges people sometimes.
Can you add new features too, not just fix old ones?
Yes, once the foundation is stable. I usually recommend stabilizing first so new features don't inherit the same bugs.
Will you sign an NDA?
Yes, before I look at anything.
