E-commerce Microservices Platform

A modern, scalable e-commerce platform built using microservices architecture. This project demonstrates best practices in distributed systems design, containerization, and cloud-native development.

Architecture Overview

The platform consists of the following microservices:

• User Service (Java/Spring Boot): Handles user authentication, registration, and profile management
• Product Service (Java/Spring Boot): Manages product catalog and inventory
• Order Service (Python/FastAPI): Processes customer orders and manages order lifecycle
• Notification Service (Node.js): Handles system notifications and communications

Tech Stack

• Backend Services: Java (Spring Boot), Python (FastAPI), Node.js
• Database: PostgreSQL, MongoDB
• Authentication: JWT-based authentication
• API Gateway: API Gateway for routing and load balancing
• Container Orchestration: Kubernetes
• Infrastructure as Code: Terraform
• CI/CD: GitHub Actions
