January 2025 monthly summary focused on delivering robust backend improvements, secure API governance, and a complete frontend board-detail experience. Key backend work unified API robustness with pagination and global exception handling, added logical deletion support, and advanced security with role-based access control and authors/admin-only modification rights. Frontend delivery included a final board detail feature with fetch/delete APIs and an improved chat timestamp display using locale-aware formatting. Overall, these efforts reduce operational risk, improve data integrity, elevate user experience, and strengthen the foundation for scalable collaboration across Honeyboard server and client.

December 2024 Monthly Summary — zyu22/honeyboard-server Key features delivered: - Implemented API endpoints for algorithm guides and problems with robust authentication (JWT/OAuth2) and S3 storage integration; also included project management improvements. Major bugs fixed and quality improvements: - Refactored authentication flow in AlgorithmGuideController to use @CurrentUser, with additional tests and logging for better reliability. - Resolved merge conflicts and refined API semantics, including 204 error handling, inclusion of title in getAllAlgorithmGuide, and implementation of logical deletion with a default current version. Overall impact and accomplishments: - Strengthened security and data lifecycle management for algorithm content, enabling secure storage, role-based access, and reliable content lifecycle operations. - Increased test coverage and observability, reducing regression risk and improving maintainability. - Accelerated feature delivery for content authors and learners, contributing to faster go-to-market and better learning resources. Technologies/skills demonstrated: - Spring Boot / Spring Security (JWT/OAuth2) authentication, REST API design, AWS S3 storage integration. - Code refactoring for cleaner architecture (using @CurrentUser), test automation (unit/integration tests), and enhanced logging. - Version control discipline, conflict resolution, and semantic API changes (logical deletion, 204 handling).
