Polish AI-Built Mobile App

I used an AI generator to spin up a cross-platform mobile app and now have working builds for both iOS and Android. The core idea is solid, but several features feel rough: screens load slowly, a few buttons do nothing, and overall reliability just isn’t where it needs to be for the App Store or Google Play. I’m looking for a seasoned mobile developer who can dive into the existing codebase, identify what the AI scaffolding missed, and get everything production-ready. What I need you to do • Audit the current project for stability, performance, and best-practice architecture. • Fix or refactor broken flows (possibly user authentication, data sync, or push notifications—happy to explain what I’ve noticed as we walk through it). • Polish UI/UX so the app feels native on both platforms. • Run end-to-end tests, squash any crash reports, and deliver ready-to-submit builds. • Hand back clean, documented code so future updates are straightforward. I’m open to whatever toolchain makes sense—whether that’s Xcode and Swift, Android Studio with Kotlin, React Native, or Flutter—as long as the end result passes review on both stores. Let me know how you’d approach the cleanup, what similar rescue jobs you’ve handled, and how quickly we could go from “almost there” to “live.”
