A full-stack multi-vendor e-commerce platform with separate storefront, seller, and admin experiences. Built with React, React Router, and Recharts on the frontend and Node/Express + MongoDB on the backend, with JWT auth and rate-limited APIs. Sellers manage their own catalog and orders through a dedicated dashboard while admins oversee the marketplace — all wrapped in a polished, purple-accented storefront with product browsing, cart, and checkout flows.
