E-commerce Application

This project is a scalable e-commerce platform built using a microservices architecture, designed to handle product listings, orders, customer accounts, payments, and more. It leverages robust backend frameworks, modern frontend technologies, and a secure user authentication system.

The application is structured with the following technologies:

  • Backend: Spring Boot for core microservices
  • Frontend: Angular
  • Microservices Management: Spring Cloud
  • User Authentication: Keycloak
  • Analytics & Reporting: Django for enhanced data visualization
