I’m looking to have a fully functional multi-vendor marketplace app built for both iOS and Android. The platform will focus exclusively on physical goods and must accommodate three distinct user roles—Admin, Vendor, and Customer—each with the permissions you’d expect (product management for vendors, order oversight for admins, seamless shopping for customers). Core features I need implemented: • Robust product search with filters so shoppers can narrow down items quickly. • User reviews and ratings tied to products and vendors to build trust. • A secure payment gateway that supports major cards and mobile wallets, processes split payouts to vendors, and logs transactions for admin reporting. I’d like a clean, intuitive UI plus the usual account management basics (sign-up, login, password reset). A functional prototype that passes TestFlight / internal beta on Android is the initial milestone; after feedback rounds, we’ll refine UX and squash any edge-case bugs before store submission. If you’re comfortable handling cross-platform frameworks such as Flutter or React Native, integrating RESTful APIs, and managing vendor/admin dashboards, I’d love to see your approach and timeline.
