I’m building a Utility-focused Android application and I need a seasoned mobile developer to take it from concept to a polished release. Although the core of the app is utility-based, users must be able to create an account with a straightforward email/password login, add items to a Shopping cart, and complete purchases through a seamless Payment gateway integration. Product listings are not part of this project, so you can concentrate on the cart and secure checkout flow rather than catalogue management. The workflow I’m picturing is simple: a new user signs up or logs in, browses the in-app utilities, drops a service or digital good into the Shopping cart, and pays without ever leaving the application. Reliability, clean UI, and compliance with Google Play policies are essential. I’m open to Kotlin or Java as long as the codebase is well-structured, documented, and easy to maintain. Deliverables • Production-ready APK and source code • Integrated, tested email/password authentication • Fully functional Shopping cart and Payment gateway integration with test credentials passed • Brief setup guide and API keys placeholder file so I can re-point to my own endpoints later Once the above items meet functional testing and compile error-free in Android Studio, the project will be considered complete. If this sounds like your wheelhouse, let’s get started.
