Native iOS Developer Needed

I need an experienced developer to convert my existing Base44 application, Influenced Up, into a genuine native iOS app and get it approved by Apple. The app is already built, and I can provide the exported source code and project access. My Apple Developer account and App Store Connect listing are already set up. My previous build was rejected, so I need a new build that is properly developed, tested, and ready for submission. Project Requirements Convert the existing app into a native iOS application, not a WebView. Preserve existing functionality and integrations, including Stripe. Test thoroughly on real devices and fix bugs. Review security, privacy, and Apple compliance. Configure TestFlight and handle App Store submission. Resolve previous rejection issues and help secure approval. Looking for someone experienced with React Native, Expo, Swift, and successful App Store launches. Please share examples of apps you have launched. I want someone efficient, experienced, and results driven who can complete this project quickly without cutting corners. Please include your estimated timeline and fixed price. This is a one time project, not a long term contract. I have additional apps planned that may create opportunities for future projects.
