Cross-Platform Ecommerce App

I need a complete ecommerce mobile application built for both iOS and Android. The app will be dedicated to selling physical goods and should feel fast, modern, and secure from the first tap through checkout.

Core functionality must include:
• A clean product catalog that supports multiple images, variants, and stock levels
• A smooth shopping cart flow that remembers items across sessions
• Seamless payment gateway integration (Stripe, PayPal, or a comparable solution) with PCI-compliant handling of card data

Beyond those essentials, I want intuitive search and filtering, push-notification support for order updates, and a lightweight analytics hook so I can track sales and user behavior. An admin console—whether web-based or baked into the app—should let me add products, change pricing, and view orders in real time.

Deliverables
1. Universal codebase for iOS and Android (React Native, Flutter, or similar) fully compiled and deployable to App Store and Google Play
2. API documentation or Postman collection covering every endpoint
3. Tested payment flow in sandbox and live modes
4. Source code in a private Git repo with clear build instructions
5. A short video walkthrough of the finished app

Acceptance criteria
• App installs and opens without crashes on recent iOS and Android devices
• Catalog, cart, and checkout work end-to-end, processing at least one live transaction
• UI matches supplied Figma designs within reasonable pixel tolerance
• All text and images load from the backend, not hard-coded

Physical products are the only focus for now—no digital downloads or service bookings required. If you have relevant live examples or code snippets, feel free to include them when you submit your approach and timeline.
