I’m launching an online product marketplace and need a developer who can take it from concept to a production-ready platform. The absolute must-have for the first release is a fully integrated, secure payment system that protects both buyers and sellers—Stripe or PayPal experience is ideal. You’ll architect the back end, build the front end, and connect everything so vendors can list items, shoppers can add products to a cart, and payments flow smoothly to completion. A clean admin panel for managing users, products, and transactions is part of the scope. While user reviews, ratings, or in-platform messaging aren’t essential for the initial milestone, I may add them later, so structuring the codebase for easy feature expansion will earn extra points. Deliverables • Deployed product marketplace (web) with secure payment gateway • Admin dashboard + vendor onboarding • Clear, commented source code in Git • Short hand-over document detailing setup, APIs, and next-step extensibility If you’ve built marketplaces before, especially those handling real-money transactions, I’d love to see examples and hear how you ensured security and scalability.
