I’m looking for a developer who can build a production-ready Android application whose core function is a paid subscription system. The app will present users with two plan choices—weekly and monthly—and process every renewal through UPI, so the flow must be fully compliant with India’s recurring-payment guidelines. You’ll need to implement a clean onboarding screen that leads directly into the UPI checkout, enforce automatic access control based on the active plan, and surface a simple “Manage Subscription” area where users can upgrade, downgrade, or cancel at any time. Kotlin in Android Studio is preferred, but I’m open to Java if that speeds delivery and keeps the codebase maintainable. Please package the final APK, all source files, and a brief README that explains build steps, UPI configuration, and where to adjust plan pricing in the code. Once I can install the APK, activate a weekly plan with my own UPI ID, and see the pay-wall lift automatically, the project is complete.
