Complete Cross-Platform Purchase-Enabled App

I already generated an initial codebase with Claude—part React-style JSX components and part .NET MAUI C#. It runs, but the AI left several inconsistencies and half-wired features. I now need an experienced developer to step in, clean things up, and turn the concept into a fully functional mobile application for both iOS and Android with working in-app purchases.

Scope of work
• Audit the existing JSX and MAUI code, document gaps, and refactor where needed so the two layers work together smoothly.
• Implement, test, and sandbox-verify in-app purchase flows on both platforms, then prepare the production configuration.
• Handle standard mobile essentials—build configs, signing, store-ready assets—so I can submit directly to the App Store and Google Play.
• Deliver a clean, compile-ready repository with comments and a short README describing build steps and any third-party libraries used. and launce the app for me


Ownership & confidentiality
I will provide a simple mutual NDA at kickoff. At final hand-off you transfer 100 % ownership of all code, assets, and build scripts to me, and send the full repository (no obfuscation or minification of source). No portions of this work may be reused or published elsewhere without my written consent.

Acceptance criteria
1. The code compiles without error in Visual Studio / Xcode / Android Studio using the supplied README.
2. In-app purchases pass Apple/Google review in their respective test environments.
3. Final source and project files are delivered, and the signed NDA & IP transfer are complete.

If this stack is in your wheelhouse and you’re comfortable signing the NDA, let’s get started.
