I’m building a full-featured grocery delivery service and need an end-to-end mobile solution that runs natively on both iOS and Android. The app must let customers create an account, browse products, pay in-app and follow their order in real time. Delivery drivers should receive route-optimized assignments, while grocery-store staff need a simple way to confirm, pack and hand off orders. Essential features • Secure user registration / login • Integrated payment gateway for cards and wallets • Live order-tracking visible to customers and drivers Primary user roles • Customers • Delivery drivers • Grocery store staff What I expect to receive • Two store-ready builds (App Store & Google Play) with matching functionality • Clean, well-commented source code and API docs • A brief hand-off session so I can run the apps locally, update products and monitor orders without developer intervention If you have proven experience deploying similar logistics or on-demand apps, let’s talk timelines and the tech stack you recommend.
