EMI MOBILE LOCK App Development

I need a skilled Android developer to build a straightforward e-commerce application from the ground up. The primary goal is to let shoppers browse a product catalog, add items to their cart, and check out securely, all within a clean, modern UI that feels native to Android.

At launch the app must include:
• User authentication so customers can sign up, sign in, and manage their profiles via email or Google login.
• A searchable, filterable product catalog that pulls data from my existing REST-based back-end.
• Payment-gateway integration (Stripe preferred, though I’m open to your expert suggestion) with proper handling of PCI-compliant tokenization, order confirmation, and error states.

I will provide the API endpoints, product images, and brand guidelines. You will handle Android UI/UX, local data caching, and integration testing. Clean, well-commented Kotlin code, MVVM architecture, and Jetpack components are strongly preferred for future maintainability.

Please outline your estimated timeline, any similar e-commerce apps you’ve shipped, and how you plan to secure user data and transactions. Once we agree on scope, we can break the work into milestones (authentication, catalog, checkout) so both sides stay on schedule.
