Cross-Platform E-Commerce Mobile App

I need a full-featured e-commerce mobile application built for both iOS and Android. The core goal is to give shoppers a smooth, secure experience from product discovery right through to checkout, while providing me with an easily managed back-end.

Here’s the scope as I see it:

• Design & UX that feels native on both platforms.
• Stable, well-structured code—Swift or Objective-C on iOS, Kotlin or Java on Android, or a proven cross-platform stack such as Flutter or React Native if that shortens time-to-market without sacrificing performance.
• Product catalogue, search, wish-listing, cart, and secure payment gateway integration.
• Customer accounts with order history and push notifications.
• Basic admin interface or API endpoints so I can upload products, adjust pricing, and view orders without digging into the code.

Deliverables
1. Compiled builds ready for App Store and Google Play submission.
2. All source code with clear documentation.
3. A brief hand-over session or document explaining deployment, environment variables, and how to add future features.

Acceptance criteria
• Apps install and run without crashes on current iOS and Android versions.
• Checkout flow completes successfully with a test payment.
• Product and order data sync correctly between the apps and the back-end.

Timelines and milestones are flexible; quality and maintainability come first. If anything in the outline needs clarification, let’s discuss it so the final product meets both our expectations.
