Over a two-month period, Je Kang developed foundational data science training materials in the ryo-ngked/data-science-training-2025 repository. He established a modular project structure with clear documentation, enabling faster onboarding and maintainability. Je created a series of Jupyter notebooks focused on data cleaning, including missing value handling, scaling, normalization, date parsing, and encoding, using Python, Pandas, and NumPy. His approach emphasized reproducibility and domain-agnostic workflows, providing templates and examples for analysts and data scientists. By removing obsolete files and aligning documentation, Je ensured a clean, organized codebase that supports future expansion and standardized data preparation practices for the team.
