Bazaar - Multi-Vendor Ecommerce Marketplace Platform
Bazaar is a full-stack marketplace platform designed to connect customers with independent sellers through a complete digital commerce ecosystem.
The platform provides dedicated experiences for buyers, sellers, and administrators, enabling product discovery, store management, order processing, and marketplace operations.
๐ฏ The Problem
Small and independent sellers often struggle to establish an online presence and reach customers without building their own ecommerce infrastructure.
Customers also need a trusted marketplace where they can discover products, compare sellers, place orders, and track purchases from a single platform.
๐ก The Solution
I built Bazaar as a complete multi-vendor ecommerce ecosystem with three major user experiences:

- โธSearch products and brands
- โธAdd items to cart
- โธComplete checkout

Seller Portal
- โธSeller onboarding
- โธStore management
- โธProduct creation and inventory management
