Hi there, I’ve reviewed your requirement and it aligns very closely with platforms I’ve already built. I’ve previously delivered cross-platform marketplace applications with multiple user roles (customers, vendors, service providers) and a chat-first transaction flow, so this isn’t new ground for me. How I’d approach your build: • Single codebase using Flutter • Role-based architecture to cleanly separate customer, shop owner, and service provider experiences • Marketplace features for physical + digital product listings, media uploads, and deal closing inside the app • Real-time chat with file sharing, voice notes, and in-app video calling (WebRTC) • Secure authentication, scalable backend APIs, and a UI that feels native on both iOS and Android I’m comfortable picking up from wireframes and moving fast once assets are shared. I can also walk you through similar marketplace and chat-heavy apps I’ve shipped and explain the technical decisions behind them. Happy to discuss the preferred tech stack and timeline when you’re ready. Regards, Shiv
