Worked on the swosu/SwosuCsPythonExamples repository to prepare and refine a dataset supporting CS1 Spring 2025 data visualization needs. Delivered two features: initializing the 2025_sp_cs1.txt file with a placeholder entry and subsequently enhancing data completeness by appending last names to existing first names. Focused on text-based data management and documentation, the work emphasized accuracy and readiness for upcoming demos and analytics. Leveraged skills in dataset preparation, basic data manipulation, and version control, ensuring clear commit histories and collaborative workflows. No bugs were reported or fixed during this period, reflecting a targeted and stable approach to feature delivery and documentation.
