Android Ecommerce App

I’m building a new mobile storefront for physical products and need a polished ecommerce app that ships on Android. Core requirements are already defined, so I’m looking for someone who can move quickly from design through store submission while keeping the codebase clean and well-documented.

Essential features
• User account management (email, social sign-in, profile editing)
• Payment gateway integration for secure checkout (Stripe or a comparable SDK you recommend)
• Product reviews and star ratings visible on each item page

Scope of work
You’ll handle the complete mobile build, hook into my existing REST/GraphQL endpoints, implement the three features above, and ensure smooth performance across recent Android versions. I’m open to native Swift/Kotlin or a proven cross-platform stack such as React Native or Flutter—choose whichever lets you meet Google Play guidelines without compromise.

Deliverables
1. Production-ready Android apps uploaded to TestFlight and an internal Play track
2. All source code in a private Git repo with clear setup instructions
3. A short handover document covering build steps, environment variables, and store listing assets

Quality bar
The UI must be responsive, the checkout flow must pass test transactions in sandbox mode, and reviews/ratings have to sync correctly with the backend. Final acceptance happens once the apps are approved for public release in both stores.

If this matches your skill set, tell me which tech stack you’d pick and an estimated timeline for each milestone so we can get started right away.
