Milestones
List view
## Scope This milestone focuses on delivering the **fully deployed and documented version (100%)** of the Backend API. The system must be complete, stable, and publicly accessible, serving as the backbone for all connected clients (Mobile, Web, and Cross-Platform). It must adhere to **Domain-Driven Design (DDD)** and **Layered Architecture**, ensuring maintainability, scalability, and alignment with enterprise-grade backend standards. --- ## Requirements 1. **Full Domain & Application Implementation** - Complete all **bounded contexts** and **aggregates** defined in the strategic DDD model. - Ensure all use cases and services are implemented and validated. - Verify business rules, invariants, and event flows within each aggregate. 2. **Layered Architecture Completion** - Ensure all architectural layers are complete and properly decoupled: - **Domain Layer:** Entities, Value Objects, Repositories Interfaces. - **Application Layer:** Use Cases / Services. - **Infrastructure Layer:** Database, Adapters, Persistence, Configurations. - **Interfaces Layer:** REST Controllers / Resources. - Maintain dependency direction (Domain → Application → Infrastructure → Interfaces). 3. **API Exposure & Integration** - Deliver all planned REST endpoints, including CRUD operations, authentication, and cross-module interactions. - Validate full integration with front-end clients (Mobile Android, iOS, Flutter). - Apply consistent request/response formats and HTTP status handling. - Ensure proper use of DTOs, Mappers, and Resource Assemblers. 4. **Database & Persistence** - Finalize schema and relationships for all modules. - Optimize database queries and indexes. - Provide updated migration scripts or schema export (SQL file). 5. **Security & Configuration** - Implement **JWT-based authentication and authorization** (if not completed in Sprint 1). - Secure all endpoints according to user roles and access scopes. - Ensure sensitive data (tokens, credentials) is safely handled via environment variables. 6. **Deployment (100%)** - Deploy the API to a **public environment** (e.g., Railway, Render, Azure, AWS, or similar). - The deployed service must be accessible through a public URL. - Document deployment steps, environment variables, and CI/CD pipeline setup (if applicable). 7. **API Documentation** - Complete **Swagger / OpenAPI 3.0 documentation** with all endpoints, schemas, and examples. - Host documentation publicly (via Swagger UI or integrated docs route `/swagger-ui`). - Include description of authentication flow, parameters, and sample responses. 8. **Testing & Validation** - Write **unit and integration tests** for core use cases and controllers. - Verify successful backend integration with connected clients. - Provide **Postman collection** or equivalent testing evidence. 9. **Project Documentation** - Update the **README.md** with system overview, tech stack, and deployment details. - Include diagrams: - **C4 Container Diagram** - **Component Diagram** (per context) - **Database ER Diagram** - Add architecture decision records (ADR) if applicable. --- ## Deliverables - **Fully functional and deployed backend API (100%)** - **Publicly accessible API endpoint** - **Complete Swagger/OpenAPI documentation** - **Database schema and migration files** - **Postman collection or testing evidence** - **Updated README with deployment and architecture documentation** - **C4 + ER diagrams** --- ## Technology Stack - **Language:** Java 21 - **Framework:** Spring Boot 3.5 - **Architecture:** Domain-Driven Design (DDD) + Layered Architecture - **Build Tool:** Maven - **Persistence:** Spring Data JPA + Hibernate - **Database:** PostgreSQL / MySQL - **Security:** Spring Security + JWT - **API Documentation:** Springdoc OpenAPI / Swagger UI - **Deployment:** Railway / Render / Azure / AWS - **Testing:** JUnit 5 + Mockito + Integration Tests --- ## Notes - This milestone represents **Sprint 2 (Sprint Review)**. - The backend must be **100% functional, deployed, and documented** for evaluation and client integration. - Focus on **stability, scalability, and full alignment with the system architecture**. - Ensure the repository contains only the **backend source code**, **deployment configuration**, and **technical documentation**.
