Android E-commerce App Development

I’m building a dedicated Android application whose sole focus is e-commerce. The goal is for shoppers to browse, add items to a cart, and check out smoothly on their phones, so I need an experienced mobile developer who can take the idea from first mock-ups through a publish-ready APK. Here’s what I have in mind: • A clean product catalogue with search and category filters • Secure cart and checkout flow (payment gateway suggestions welcome) • Basic order history / status screen • Lightweight admin access for adding or updating products Because this is Android-only, I expect everything to be coded natively—Kotlin or Java inside Android Studio—while keeping the architecture modular enough to connect to whichever back-end or API I ultimately choose. Deliverables 1. Interactive Figma (or similar) prototype for approval 2. Full Android Studio project with well-commented source code 3. Signed APK ready for Play Store upload 4. One-page setup & deployment guide I’ll test by installing the APK on multiple devices and running through a complete purchase; the flow must stay stable and responsive throughout. Let me know your preferred stack, any e-commerce apps you’ve shipped before, and an estimated timeline for the first working build.
