Architecture Overview

This project features a decoupled microservices architecture. The **Catalog Service** handles product data using MongoDB, the **Order Service** manages transactions with PostgreSQL, and the **Payment Gateway** is mocked for demonstration purposes.

Key Features

• Real-time inventory updates via a message broker (Kafka).
• JWT-based authentication for user and admin roles.
• Responsive design for mobile and desktop browsing.

The frontend is a single-page application that communicates with the API Gateway to interact with the backend services.
