I’m ready to build a full-featured grocery delivery platform that runs smoothly on both Android and iOS. The system must handle several physical hubs (warehouses or dark stores), letting each location receive orders, manage stock in real-time, and dispatch drivers with live GPS tracking. Core features I need baked in from day one include: • User profiles for shoppers, drivers, and store managers, each with the right permission set. • Secure online payment, supporting the usual cards and wallets plus an easy-to-extend gateway layer. • A promotions engine so I can push coupon codes, flash sales, and other offers without another app release. • Instant order-status updates and real-time driver location on the customer’s map view. • Hub inventory tracking that syncs back to the app so customers only see what’s actually on the shelf. I’m aiming for native-quality performance, whether that’s via Kotlin/Swift or a proven cross-platform stack such as Flutter or React Native—open to your recommendation so long as the UX stays snappy and both stores approve the builds. Deliverables I’ll review for acceptance: 1. Android & iOS apps compiled, signed, and ready for store submission. 2. A lightweight web or desktop console where store managers can update stock, assign drivers, and create promo codes. 3. Source code and documentation covering build steps, environment variables, and any third-party services used. 4. A quick demo video showing order flow from customer checkout through driver delivery with live tracking. If you’ve shipped similar logistics or food-delivery apps and can walk me through a brief roadmap to MVP, let’s talk timelines and milestones right away.
