December 2024 – Focus: documentation-driven improvement to accessibility and guidance for the techeer-sv/2024-Team-Joe-backend-study project. Delivered one feature: a markdown document that links to the Notion page for 'Effective JAVA 12', enabling quick access to best practices and references without touching production code. No major bugs fixed this month. Impact: accelerates onboarding by centralizing guidance, reduces time to locate authoritative references, and improves auditability of changes through a clear commit trail. Technologies/skills demonstrated: markdown documentation, repository organization, Notion link integration, and commit-level traceability across the project.

November 2024 – techeer-sv/2024-Team-Joe-backend-study: Delivered the Chapter 7–9 Assignment Submission Materials feature for the backend study project. The backend now provides PDFs and Markdown entries with Notion links to support assignment submissions for chapters 7, 8, and 9, enabling a centralized and referenceable submission workflow for students and instructors. The work is tracked with explicit per-chapter commits, improving traceability and rollback options. No major bugs reported this period.
