During a two-month period, Halley developed two Jupyter Notebooks for the halley1116/2025_DA_study repository, focusing on data analysis and natural language processing. In the first project, Halley built an exploratory data analysis workflow for insurance data using Python and pandas, enabling users to investigate relationships between medical and lifestyle factors. The second notebook introduced an end-to-end sentiment analysis pipeline, integrating data preprocessing, visualization with word clouds, and NLP modeling using FastText and logistic regression. Both projects emphasized reproducibility and extensibility, providing structured, well-documented code that supports further analytics and experimentation without reported bugs or quality issues.
