On-Demand Car Wash Platform Development Video bid only

We are hiring an experienced mobile and backend developer or agency to build an on-demand doorstep car and bike wash platform comprising a Customer App (iOS/Android), Washer/Partner App (iOS/Android), and a Web Admin Dashboard. The system requires phone OTP and social authentication, multi-vehicle profiles, geolocation-based address picking, service package selection with dynamic pricing by vehicle type, instant or scheduled slot bookings, integrated payment gateways, and live job status tracking. For service providers, the app must include incoming job alerts, turn-by-turn map navigation to the customer, "before and after" photo proof uploads, and a daily/weekly earnings dashboard. The central web admin panel must manage booking dispatches, washer KYC approvals, coupon and discount configurations, commission splits, and revenue reporting. Our preferred tech stack is React Native or Flutter for cross-platform mobile apps, Node.js (NestJS or Express) with MongoDB/PostgreSQL on the backend, and Next.js or React for the admin console. ATTENTION - BOT FILTER & PROPOSAL REQUIREMENT: Generic, templated, or text-only proposals will be rejected immediately without review. To be considered, your bid must include a link to a short 1-to-2 minute Loom or Google Drive video introducing your team, showcasing 1 or 2 live on-demand booking apps you have previously built, and confirming your recommended architecture and delivery timeline. Along with your video link, please include your total fixed-price quote and realistic milestone schedule to get started.
