I need a full-featured e-commerce solution deployed on both iOS and Android. The core customer app must showcase rich product listings, let shoppers pay through an integrated gateway, and invite them to leave authentic reviews after purchase. Alongside the customer-facing app, I also require: a lightweight driver/delivery app so couriers can receive orders, update statuses in real time, and navigate to addresses; plus a secure admin panel where I can manage inventory, prices, users, promotions, and review analytics. To keep everything maintainable, please use a modern cross-platform stack (Flutter, React Native, or a solid native duo of Swift and Kotlin—your call, just explain your choice) connected to a scalable backend with REST or GraphQL APIs. Push notifications, basic order tracking, and App Store/Google Play submission support are expected. Deliverables • Source code for customer, delivery, and admin apps • Ready-to-deploy backend with documentation • UI/UX assets and build files • Live builds published to both stores and a brief hand-over session Acceptance will be based on: smooth browsing of products, successful test transactions, visible user reviews, real-time order updates in the delivery app, and full control of catalogues from the admin panel. Let me know your timeline and any questions, and we can get started.
