During March 2025, Hhmp2005 focused on improving the maintainability of the TCS-2021/Data-Mining-Project repository by restructuring its codebase. They reorganized key files, moving Diabetes Missing Data.csv to a more logical Datasets directory and relocating preprocessing.py to a dedicated preprocessing application folder. This work, implemented using Python and CSV file management skills, did not alter functionality but established a standardized layout for datasets and scripts. The changes addressed code organization challenges, making the project easier to navigate and setting a foundation for future development. The depth of work was limited to structural improvements rather than new features or bug fixes.
