Chieh Teng developed a suite of data science and machine learning features for the HWTeng-Teaching/202509-ML-FinTech repository over four months, focusing on reproducible analytics and onboarding efficiency. He created Jupyter Notebook workflows for clustering, regression, and classification tasks, integrating datasets such as Boston housing, college, and stock market data. Using Python, pandas, and scikit-learn, Chieh established documentation scaffolding and reusable templates that streamlined experimentation and facilitated knowledge transfer. His work emphasized maintainable project structure, clear documentation, and ready-to-run examples, enabling faster hypothesis testing and collaboration. The depth of his contributions supported both technical rigor and business value.
