Feb 1, 2025February 2025 – SOEN490-SportsApp/SportsApp monthly summary Key features delivered: - User Friendship Deletion and Unfriending: End-to-end unfriending workflow with a new API endpoint, backend service method, and transactional deletion ensuring removal of the friendship relation and related records from both users. Added unit tests to validate behavior. - Messaging Microservice Core: Established core messaging capabilities with OpenAPI specification, WebSocket support, DTO definitions for requests/responses, core message processing and retrieval, along with error handling and mapping configuration. - Code Quality Improvements: Refactors to remove unused imports in the User model and remove an unused enum in the messaging service to improve maintainability. Major bugs fixed: - Ensured data integrity during unfriending by making the deleteFriend operation transactional, preventing partial deletions and inconsistencies across user records. - Increased test coverage for the unfriend endpoint through dedicated unit tests to prevent regressions. Overall impact and accomplishments: - Strengthened social graph integrity and user trust by delivering reliable unfriending functionality. - Enabled real-time messaging capabilities to boost user engagement and responsiveness. - Improved maintainability and code health, reducing technical debt and enabling faster feature delivery. Technologies/skills demonstrated: - Backend transactional operations and service orchestration - Microservices architecture (messaging) with OpenAPI and WebSocket - DTO design, error handling, and mapping - Test-driven development with unit tests for endpoints - Code quality discipline and refactoring for maintainability

Nov 1, 2024Month: 2024-11 — Delivered secure, scalable authentication and event management capabilities across the SportsApp repository, expanding into a dedicated Event Service microservice. Implemented a token-based login system backed by Keycloak, added login and refresh endpoints, updated security configuration, and established a token refresh flow. Bootstrapped and expanded the Event Management Microservice with Docker setup, MongoDB persistence, REST endpoints for creating and retrieving events, Swagger/OpenAPI integration, mappings, validation, and tests to improve maintainability and quality. Resolved security integration gaps by adding the refresh endpoint to the securityFilterChain, and enhanced test coverage. Refined data models with a new requiredSkillLevel field (EnumSet) for events to improve validation and querying. This combination delivers secure user onboarding, scalable event management, faster feature delivery, and higher quality with better test coverage.
