Worked on the eunbi-kim/24_2_W_SeProj repository to lay the foundation for a new To-Do List feature, focusing on documentation and architectural planning. Created a task management diagram using XML to visually map out the feature’s structure and user experience, ensuring alignment among stakeholders and reducing implementation risks. Emphasized clear documentation practices to enhance repository traceability and support future development efficiency. No bug fixes were addressed during this period, as the primary focus remained on preparing comprehensive planning artifacts. Demonstrated skills in documentation and diagramming, contributing to a more organized and maintainable codebase for subsequent feature development.
