I need a React Native specialist to build a full-featured grocery e-commerce application that runs smoothly on both iOS and Android. The core idea is straightforward: customers should be able to browse a fresh-produce catalog, add items to a cart, and complete checkout without friction. Here is what matters most to me: • A clean, searchable product catalogue optimised for frequent updates and large inventories. • A reliable shopping-cart flow that keeps state even if the user momentarily leaves the app. • Fast, secure payment-gateway integration so buyers can pay with cards or popular wallets. • Solid performance on mid-range devices and an intuitive UI that looks native on each platform. I’ll supply brand colours, basic wireframes and API endpoints for inventory and orders. You’ll turn these into a polished, production-ready React Native build, connect the endpoints, and package the final binaries (IPA & APK) for TestFlight / Play Console submission. If you’ve shipped React Native e-commerce apps before—especially grocery or quick-commerce—let’s talk.
