React Native app backed by a RESTful e-commerce API handling product catalog, cart, and order management. Delivery scheduling (Express, Next Day, Park & Pick Up) is handled through a fulfillment service. Payment flows integrate Credit/Debit card, E-Payment wallets, and QRIS. The barcode/QR scanner uses the device camera to look up products in real time. Push notifications keep users updated on order status and active promotions.
