Eunbi Kim focused on enhancing system design documentation for the eunbi-kim/24_2_W_SeProj repository, building and refining draw.io diagrams to support a To-do List Management feature. Over the course of a month, Eunbi updated and aligned multiple diagram assets to reflect evolving requirements, ensuring that documentation remained accurate and actionable for onboarding and future development. The work emphasized diagramming and documentation skills, leveraging draw.io and XML to maintain clarity and consistency across design artifacts. While no bugs were addressed, the depth of diagram updates and collaborative maintenance improved repository assets, streamlining downstream development and supporting stakeholder alignment for upcoming features.
