I’m launching a food-delivery service and need a complete mobile application that runs smoothly on both iOS and Android. The core features are clear: • secure user registration / login • restaurant listings with searchable menus • real-time order placement and tracking • in-app checkout with an integrated payment gateway I’m open to the tech stack you’re most confident in—native Swift / Kotlin, Flutter, React Native, or another robust solution—as long as the final builds pass App Store and Google Play review. Design should follow current UX patterns for food delivery, with intuitive screens for browsing, cart management, and order status updates (push notifications included). On the back end, I’ll need whatever services are required to power these features—APIs, database, and basic admin access to add or update restaurants and menus. Deliverables: 1. Production-ready iOS and Android apps (source code + compiled builds) 2. Fully configured payment gateway working in test and live mode 3. Basic admin panel or documented API endpoints for restaurant management 4. Deployment support through to successful store approval If you’ve built similar apps before, please share links or screenshots. Let me know the tools you propose, any third-party services you’d integrate, and a realistic timeline to hit each milestone.
