Multi-Vendor Food Delivery Apps Development

I need four distinct components built and published within 12 days: • User app (Android) • Vendor app (Android) • Delivery-partner app (Android) • Admin panel – already live, just needs the new feature set wired in and thoroughly tested. The three mobile apps must be separate APKs on Google Play by 12 May. Core flows include sign-up/login, live menu browsing, cart & checkout, order tracking with push notifications, real-time status updates for vendors and riders, and an admin-controlled commission structure. The vendor side should support menu management, pricing, order history, and payout reporting, while the rider side handles order queue, route optimisation (Google Maps API), status toggles, and earnings summaries. Feel free to build with native Android (Kotlin/Java) or a single-codebase framework such as Flutter or React Native, as long as performance is smooth and each app is released separately. I will provide existing admin credentials, branding assets, and any third-party keys you need (payment gateway, maps, etc.). Acceptance criteria 1. All three Android apps approved on the Play Store by the deadline. 2. Admin panel fully updated, bug-free, and reflecting new app features. 3. Signed APKs, source code, and deployment documentation delivered. Full payment (INR 20,000) is released after I confirm that everything works as expected on production. If you are confident you can hit the May 12 date, let’s get started immediately.
