In October 2025, In Tae worked on the Jihye511/Ssafy_Algo_Study repository, focusing on reorganizing the project structure to support Version 2 development. He refactored directory layouts by renaming WEEKxx folders under a new ver1 hierarchy and initialized a ver2 directory with scaffolding for future testing, including a placeholder test file. Using Java and leveraging skills in code organization and file management, he improved the repository’s modularity and maintainability. Although the work centered on foundational restructuring rather than feature delivery or bug fixes, it established a clear, versioned framework to streamline future enhancements and support ongoing collaborative development.
