I want to launch a full-featured consumer-to-consumer marketplace available on both Android and iOS. The app has to let everyday users list items for sale, browse other people’s listings, chat safely in-app, and complete purchases with a secure payment flow. Think of it as a streamlined blend of classifieds and e-commerce in one place, but mobile-first. Key functions I need included • Buyer and seller registration with profile photos, ratings and written reviews • Product listing creation: photos, descriptions, price, location and optional tags • Powerful search, category filtering and location-based discovery • Real-time in-app messaging with push notifications • Secure checkout (card, wallet or other mainstream gateway) and order history for both parties • Dispute, refund and reporting mechanisms, plus a lightweight admin web panel for me to moderate content, manage users and pull analytics I’m flexible on tech stack as long as the result is native-quality on both platforms; Flutter, React Native or two separate native builds are all acceptable. The backend can be Node, Django, Laravel or similar, provided it is documented, RESTful (or GraphQL) and ready for cloud deployment. Deliverables 1. Complete Android and iOS binaries ready for store submission 2. Source code with clear commit history 3. Backend with database schema and deployment scripts 4. Basic admin web panel 5. Setup guide and short video walk-through showing build, deploy and key flows Acceptance criteria • All core flows (sign-up, list, search, chat, pay) pass QA on both platforms • No critical crashes or blockers during a one-week beta period • Code review shows clean architecture, modular components and inline comments If you’ve built marketplaces, social commerce apps or any large transactional mobile project, please share relevant links in your proposal along with a high-level timeline. I’m ready to move quickly once I see the right fit.
