Amy Han developed an end-to-end competing risk model comparison framework in R for the zarathucorp/blog repository, enabling rigorous evaluation of survival models using metrics such as Harrell’s C-index, Wolbers’ C-index, AUC, and Brier scores. She enhanced melanoma survival analysis reporting by refactoring R code for data preprocessing and expanding model evaluation metrics, resulting in clearer presentation within blog posts. Amy also maintained and updated the blog site, addressing asset management, index alignment, and publication date consistency using HTML and CSS. Her work demonstrated depth in statistical modeling, technical writing, and web development, supporting reproducible analytics and stakeholder-facing reporting.

April 2025: Delivered an end-to-end competing risk model comparison framework in R, including data preprocessing and performance evaluation (Harrell's C-index, Wolbers' C-index, AUC, and Brier scores), accompanied by multiple blog posts detailing methodology, results, and improved presentation of findings. Improved melanoma survival analysis reporting through refactoring and enhancements to R code for data processing, metrics, and results presentation within the blog post. Performed blog site maintenance and deployment updates, including asset changes, index alignment, and publication date consistency, and resolved site conflicts to improve reliability of releases. These efforts collectively advance decision-making through rigorous, reproducible analytics and clear stakeholder-facing reporting.
