About this Gig

Your AI-built app works in the demo. Then real users find the bugs: login breaks, data won't save, the build fails, or your API key is sitting in the browser.


I fix apps built with Lovable, Bolt, Cursor, Replit, v0 or ChatGPT, and apps left behind by other developers. I find the root cause and fix it properly, so it stays fixed.


WHAT I FIX

- Errors, crashes, white screens and failed builds

- Login, database and payment problems

- Exposed API keys and open database rules

- Slow pages and screens

- Deploy, App Store and Play Store problems


ANY STACK

React, Next.js, Node.js, Supabase, Firebase, Flutter, React Native, Python and more. Not sure about yours? Message me before ordering.


WHY ME

5+ years and 36+ apps shipped. I've kept an AI app running for 3.5 years, got a social app through App Store review on the first try, and I write database security rules with automated tests.
