I’m building a streamlined platform where people can list and purchase physical goods at a firm, fixed price—no auctions, no social-style feed. The goal is a clean, intuitive mobile app that lets sellers upload photos, set a price, and publish instantly while buyers browse, payment will be cash on pickup, barter, swapping or cash on delivery, all prices are set prices so for multiple items you will pay the same price for 1 item and it will be the same price per item if you buy 100, the savings come from how this app will connect the buyer and the seller and cut out everything in between. Key flow • Listings: photo gallery, description, price, stock status • Checkout: cash payment on pickup, or negotiation of another currency agreed upon by both buyer and seller. • Profiles: each user accumulates rating & reviews to build credibility • Search & discovery: category browsing, keyword search, location filter • Admin console: approve or remove listings, view analytics, handle disputes Tech preferences iOS and Android coverage is a must; I’m happy with Flutter, React Native, or native stacks if you make a strong case. The backend can be Node, Laravel, or any robust REST/GraphQL setup that scales. Deliverables 1. Wireframes and polished UI/UX prototypes 2. Fully functional apps for both stores, ready for submission 3. Secure backend with API documentation 4. Admin dashboard with moderation tools 5. Deployment guide and post-launch support window If you have a track record in e-commerce builds—especially fixed-price trading apps—let’s talk about timelines and the development approach you’d propose.
