Contributed to the HWTeng-Teaching/202509-ML-FinTech repository by building a suite of Jupyter notebooks and documentation scaffolding to streamline onboarding, reproducibility, and data science experimentation. Developed end-to-end workflows for data analysis and machine learning, including clustering, regression, and classification tasks across datasets such as Boston housing, college data, and stock market trends. Leveraged Python, pandas, and scikit-learn to implement feature preparation, model training, and evaluation within reproducible templates. Enhanced repository maintainability by standardizing documentation and project structure, enabling rapid experimentation and knowledge transfer for new contributors while supporting business value through accessible, well-documented analytics workflows.
