Multi-Restaurant Food Delivery Marketplace

I need a complete food-ordering marketplace that lets customers browse many restaurants and get meals delivered to their homes. The core flow is familiar: user opens the app, chooses from multiple eateries, pays in-app, then tracks the driver until the food arrives.

Key functions I must see working:
• iOS and Android consumer apps with smooth menu browsing, promo codes, real-time order status, and push notifications
• A separate restaurant web panel to receive, confirm, and update orders in real time
• Driver tracking integration (Google Maps API or similar) so customers watch the delivery on a live map
• Secure payments (Stripe, PayPal, or your recommended gateway) and basic wallet/refund handling
• Scalable backend with REST or GraphQL endpoints and basic analytics

Clean UI/UX, reliable code, and clear documentation are non-negotiable because I need to move fast—ASAP completion is my priority. If you have a ready-made base that can be branded and tweaked, tell me; otherwise outline the stack and sprint plan you propose. I will release milestones once I can install and test each major module on my own devices and server.
