I need a complete food-delivery solution that works smoothly on both iOS and Android. The core experience should mirror services like SkipTheDishes or DoorDash: users browse nearby restaurants, place an order, then watch its journey in real time from kitchen to doorstep. Essential customer-side features • Real-time order tracking tied to the courier’s GPS • Multiple payment options (card, Apple Pay / Google Pay, and an in-app wallet) • Restaurant and driver ratings with written reviews that can be flagged or replied to Restaurant portal Owners must be able to create and edit menus (items, modifiers, availability) and manage incoming orders from a web dashboard or an embedded view inside the main app. Status changes—accepted, in preparation, ready for pickup—should trigger automated notifications to both the courier and the customer. Admin console A lightweight back-office panel will let me handle onboarding (restaurants, drivers, promo codes), adjust delivery fees, and view live analytics on orders, revenue, and ratings. Tech preference I’m open to React Native, Flutter, or another cross-platform stack as long as you can demonstrate stable performance, push-notification reliability, and secure payment integration (Stripe or Braintree). A microservice backend in Node.js or Django plus a cloud database (Firebase, PostgreSQL, or similar) works for me, provided the architecture is scalable. Acceptance criteria 1. Apps pass App Store & Play Store review. 2. GPS tracking is accurate within 15 m. 3. Payments clear in test and live modes. 4. Restaurant portal updates sync across all devices in under 5 seconds. 5. Source code, documentation, and deployment scripts are handed over at project close. Please outline your proposed tech stack, timeline, and any previous work on on-demand delivery apps when you respond.
