Problem
How do you handle real-time inventory across multiple sellers at scale?
Approach
Designed and built a comprehensive MERN stack application with Socket.IO for real-time chat, MongoDB for flexible schema management, and Stripe for secure payments. Implemented role-based access control across three dashboards (user, seller, admin) and integrated Cloudinary for optimized image uploads.
What it shows
Shipped multi-vendor marketplace with concurrent user support and real payment integration
What I Was Solving
Building a scalable multi-vendor marketplace requires complex logic for user, seller, and admin roles with different permissions. Real-time communication between buyers and sellers, secure payment processing, and efficient image management were critical requirements that needed to be seamlessly integrated.
How I Approached It
Designed and built a comprehensive MERN stack application with Socket.IO for real-time chat, MongoDB for flexible schema management, and Stripe for secure payments. Implemented role-based access control across three dashboards (user, seller, admin) and integrated Cloudinary for optimized image uploads.
What This Includes
Multi-role dashboards (User, Seller, Admin)
Real-time messaging with Socket.IO
Product listing and inventory management
Stripe payment integration
Cloudinary image uploads and optimization
Responsive design across all devices
System Overview
Client applications communicate with a Node/Express API for auth, catalog, orders, and chat orchestration. MongoDB stores core marketplace data, while Stripe, Cloudinary, and Socket.IO power payments, media, and real-time messaging.
Data Model
The marketplace centers on user accounts, product inventory, cart state, orders, reviews, and chat activity. Each collection is designed to support multi-vendor ownership, payment state, and seller moderation without duplicating data.
User Flow
A shopper lands on the store, discovers a product, chats with the seller if needed, adds to cart, checks out, and then tracks the order. Sellers and admins can review catalog, orders, and support activity from their dashboards.
Background Flow
When checkout completes, payment verification triggers order creation, inventory updates, and notifications. Realtime chat events and uploads are processed separately so the storefront remains responsive.
What It Demonstrates
Launched fully functional multi-vendor marketplace
Real-time chat enabling direct buyer-seller communication
Secure payment processing with Stripe integration
Scalable architecture supporting multiple vendor types
