Marketplace Prototype

Concept

This marketplace prototype was built as a proof of concept for a multi-vendor platform where independent sellers can list products and manage their own storefronts. The focus was on validating the core user flows — browsing, searching, adding to cart, checking out, and seller-side order management — before committing to a full production build.

Key Features & Scope

The prototype covers the buyer journey end-to-end: product listings with search and category filters, a shopping cart with quantity management, Stripe-integrated checkout, and order confirmation. On the seller side, there is a dashboard for listing products, managing inventory, and viewing incoming orders. Firebase Auth handles user registration and login for both buyers and sellers. The Flutter frontend communicates with a Node.js API backed by MongoDB for flexible product data storage. While not production-ready, the prototype successfully demonstrated the feasibility of the full marketplace concept and informed the architecture decisions for the production version.
