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.
