🗺️ Roadmap & Upcoming Features

This project is under active development. The following modules are planned for the next releases:

• Phase 1: Clean API & Robustness (Global Exception Handling, DTO Pattern, Validations).
• Phase 2: Complex Relational Mapping (Many-to-Many & One-to-Many implementation).
• Phase 3: Security Layer (High Priority)
  • Implementing Spring Security 6 with JWT for stateless authentication.
  • Role-Based Access Control (RBAC): Admin vs. User permissions.
• Phase 4: Testing Suite
  • Unit testing for Service Layer using JUnit 5 and Mockito.
  • Integration testing for REST Endpoints.
• Phase 5: DevOps & Deployment
  • Containerization with Docker and Docker Compose.
  • CI/CD pipeline setup for automated deployment.
• Phase 6: External Integration (Optional)
  • Connecting to a Currency Exchange API for dynamic salary calculations.
