I want to take my online store mobile with a dedicated Android application that handles everything from browsing to checkout. The project covers end-to-end development: UI/UX design, native coding (Kotlin or Java), secure payment integration, and connection to my existing product database through a REST or GraphQL API. Key goals • A smooth, modern catalogue and search experience • Cart, wishlist, and one-page checkout with major payment gateways • Order tracking, push notifications, and basic in-app support chat • A lightweight admin panel or clearly documented hooks so I can manage inventory, prices, and promotions without touching the code Deliverables 1. Production-ready APK plus signed AAB for Google Play submission 2. Complete, well-commented source code in a Git repository 3. Brief technical handover guide outlining build steps, environment, and API endpoints The UI must follow current Android Material guidelines and run reliably down to Android 8.0. I’ll supply brand assets and endpoint documentation as soon as we start, and I’m happy to review early prototypes to keep iterations short. Let me know your preferred tech stack, any e-commerce libraries you trust, and an estimated timeline to launch.
