DetailApp is a marketplace platform connecting customers with professional detailers using a Wolt-like model: the detailer comes to you, payment is protected with an escrow system, and the entire process is documented with video proof (before/after).
The mobile app (Expo/React Native) covers the full flow for both sides: searching and filtering detailers by location, instant or scheduled bookings, live chat, loyalty points and an Apple/Google Wallet card with QR scanning on arrival.
The admin panel (Next.js) offers a real-time platform overview: detailer verification, dispute management, financial overview, KPIs and system status. A Convex backend provides reactive data without polling, automatic deletion of expired videos and a ready-made Stripe Connect integration.
Solution
React Native with Expo for one mobile codebase on both platforms, Convex for a reactive backend with zero infrastructure, and a Next.js admin panel with shadcn/ui for operational oversight. Stripe Connect for escrow, Firebase for push notifications.
Results
A complete two-sided marketplace platform – from registration and OTP verification through to completing a booking with video proof.
