E-Commerce Organiser & Payments App Build & Launch

I already have a complete Figma file that maps every screen and user flow. I now need those designs turned into a working mobile app that can be published on both the Apple App Store and Google Play.

Scope for this first release is intentionally lean so we can move fast:

• Build all screens exactly as laid out in Figma, keeping animations and micro-interactions simple.
• Implement core e-commerce features—catalogue, product detail, cart, checkout, order history—using clean, reusable code.
• Integrate Stripe for secure payments at checkout.
• Connect to a shipping service API so rates appear in real time and tracking numbers are stored against each order.

Deliverables:
1. A single codebase (React Native, Flutter, or another cross-platform framework you prefer) that compiles for iOS and Android.
2. Two store-ready builds along with concise submission notes and any required assets (icons, screenshots).
3. A brief README covering environment setup, API keys, and how to trigger a release build.

Please ensure the app is responsive across common device sizes, follows platform-specific UI conventions, and loads quickly on mid-range phones. If everything looks good after internal testing, we can discuss additional features like Apple Pay or marketing tool integrations in a follow-up phase.
