Backend e-commerce service built with Java and Spring Boot, focused on RESTful API design, modular architecture, and scalable backend system structure.
This project demonstrates backend engineering fundamentals through the design of a layered, service-oriented architecture. It focuses on clean separation of concerns, maintainability, and scalable API design principles.
The system models core e-commerce workflows including product and user management.
The application follows a layered architecture:
Controller → Service → Repository
- Controllers handle HTTP requests and route API calls
- Services contain business logic and application rules
- Repositories manage data access and persistence layer interactions
This structure ensures modularity and clear separation between system responsibilities.
- RESTful API design for product management
- REST endpoints for user management workflows
- Layered backend architecture (Controller / Service / Repository)
- Modular and maintainable codebase structure
- Scalable backend design patterns
- Separation of business logic and data access layers
