Sherry Chang developed and maintained a comprehensive suite of Jupyter Notebooks for the HWTeng-Teaching/202509-ML-FinTech repository, focusing on machine learning applications in financial technology. Over four months, she created and refined 41 feature-rich notebooks, implementing clustering, regression, and risk prediction workflows using Python, Pandas, and Scikit-learn. Her work emphasized reproducibility and maintainability through standardized naming, versioning, and repository hygiene. Sherry also produced audit-ready documentation in PDF format, ensuring traceability from exploratory data analysis to model evaluation. This approach enabled scalable collaboration, streamlined onboarding for contributors, and supported robust stakeholder decision-making in risk and credit evaluation contexts.
