Project Overview

This e-commerce platform is a full-stack application designed to provide seamless online shopping experiences. It incorporates advanced features like role-based authentication, real-time product reviews, and an admin dashboard for effective management of products, users, and orders. It also includes a payment gateway for secure transactions and supports filtering, sorting, and pagination to enhance user experience.

System Architecture

The system follows a modern three-tier architecture:

1. Frontend: Built with React and Redux for state management, providing a dynamic and responsive UI.
2. Backend: Node.js with Express serves as the backend, managing business logic and API routes.
3. Database: MongoDB stores user data, product details, reviews, orders, and role-based access control.

The architecture utilizes JWT tokens for secure and scalable role-based authentication.
