I need a skilled Android developer to turn my product catalog into a polished native shopping experience. The app will be released only on the Google Play Store, so I’d like it built with the latest Android SDK, Kotlin (or Java if you can justify the choice), and standard Material Design patterns to keep navigation familiar and intuitive. Core flow Visitors should be able to browse categories, open a product page with images and specs, add items to a cart, and move through a secure checkout that supports at least one mainstream payment gateway. A fast in-app product search is essential, and I’m keen on clean architecture so the codebase remains maintainable as the catalog grows. Data & back-end You’re free to recommend the most suitable stack for syncing inventory and orders—Firebase, RESTful APIs, or another proven option. Just be sure whatever you choose can scale and handle real-time updates without slowing the user experience. Deliverables • Full Android Studio project with readable, modular code • Signed release APK / AAB ready for Play Store submission • Basic admin or config documentation showing me how to add new products and update prices • A brief test plan or video walkthrough proving that browsing, search, cart, and checkout work end to end Please share links to any live e-commerce apps you’ve published on Android and note the tools or libraries you prefer (Jetpack, Room, Retrofit, etc.). I’m ready to start as soon as I find the right fit.
