Android E-Commerce App Development

I have an early-stage startup concept that needs to come to life as a native Android e-commerce app. The goal is to release a clean, stable MVP on Google Play that lets users log in securely, browse a product catalog, and complete purchases through a fully functional shopping cart.

Core scope
• Build the entire Android application from scratch, targeting the latest API level and following Material Design guidelines.
• Implement User Authentication (email/password with room to expand to social logins).
• Create a scalable Product Catalog with category browsing and search.
• Integrate a Shopping Cart flow that persists across sessions and culminates in a checkout placeholder screen (payment gateway wiring will be a later milestone).
• Structure the project for future cross-platform growth—while this release is Android only, I plan to add iOS once traction is proven.

Tech preferences
Kotlin, Jetpack Compose or XML layouts, Firebase/Auth + Firestore for the back-end are all welcome choices, but I’m open to alternatives if you can justify improved speed, security, or maintainability.

Deliverables
1. Android Studio project with clean, documented code.
2. APK / AAB ready for internal testing on real devices and the Play Console.
3. Brief setup notes: environment, dependencies, build steps.
4. One hand-off call or screen share to run through the codebase.

Acceptance criteria
• Smooth sign-up / sign-in flow that rejects invalid data.
• Catalog and cart actions reflected instantly and surviving app restarts.
• No crashes or major UI glitches on Android 10-14.
• Performance: first screen paint under 2 seconds on a mid-range phone.

If you can deliver this lean yet extensible MVP, let’s put this idea into users’ hands.
