⚙️ Architecture Overview

The backend applies Clean Architecture:

├─ Controller (REST API)

├─ Service (business logic)

├─ Repository (data persistence)

├─ Messaging (RabbitMQ)

└─ DTO / Mapper layer

Benefits:

• Decoupled modules
• Minimal code duplication
• Easier testing using mocks
• Smooth scalability when adding new modules

🐳 Docker Services

Service	Purpose
PostgreSQL	Database for orders, users, balance, address, inventory
RabbitMQ	Asynchronous transaction processing
Spring Boot	Backend API
React	Frontend

All containers and networking are configured in docker-compose.yml.
