Bazaar - Multi-Vendor Marketplace Platform

A full-stack multi-vendor marketplace ecosystem enabling buyers, sellers, and administrators to manage shopping, selling, and marketplace operations through a scalable commerce platform.

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.

๐ŸŽฏ 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.

๐Ÿ’ก The Solution

I built Bazaar as a complete multi-vendor ecommerce ecosystem with three major user experiences:

Buyer Portal

  • โ–ธBrowse products, categories, and stores
  • โ–ธSearch products and brands
  • โ–ธAdd items to cart
  • โ–ธComplete checkout
  • โ–ธTrack orders
  • โ–ธManage wishlist
  • โ–ธCommunicate with sellers
  • โ–ธSubmit reviews

Seller Portal

  • โ–ธSeller onboarding
  • โ–ธStore management
  • โ–ธProduct creation and inventory management
  • โ–ธOrder handling

  • โ–ธSeller dashboard

Admin Dashboard

  • โ–ธMonitor marketplace activity
  • โ–ธManage products and categories

  • โ–ธNext.js

Backend Architecture

Built a dedicated NestJS REST API backend with:

  • โ–ธModular architecture

  • โ–ธRole-based authorization
  • โ–ธBusiness logic separation

Database

  • โ–ธUser management

  • โ–ธStores
  • โ–ธOrders
  • โ–ธMarketplace data

Authentication & Security
