Developed a suite of Jupyter notebooks and documentation in the ryo-ngked/data-science-training-2025 repository to support data science training and onboarding. The work included authoring Python-based materials covering arithmetic, variables, data types, and functions, as well as hands-on exercises using the Titanic dataset. Expanded the project with end-to-end workflows for data cleaning, preprocessing, and visualization, featuring practical exercises on missing value imputation, scaling, date parsing, and character encodings. Leveraged pandas and Seaborn to demonstrate reproducible data analysis and visualization techniques. All contributions emphasized clear documentation, structured progress tracking, and reusable assets to accelerate learning and improve data quality.
September 2025: Delivered two end-to-end notebooks in ryo-ngked/data-science-training-2025 that advance data cleaning, preprocessing, and visualization workflows. The Data Cleaning and Preprocessing Notebook Series provides practical exercises, checks, and techniques for handling missing values, scaling, date parsing, encodings, and inconsistent data entry, while the Data Visualization with Seaborn Notebook guides environment setup, loading FIFA rankings data, and plotting basic visualizations. No major bugs were reported this month; all work was committed with clear traceability. Business impact includes faster data preparation, improved data quality, and reusable training assets that shorten time-to-insight for data science initiatives. Technologies demonstrated include Python, Jupyter notebooks, pandas-based preprocessing patterns, data quality checks, and Seaborn visualizations.
