Andrea Chi Zhang contributed to the PSIAIMS/CAMIS repository by building features that improved data organization, reproducibility, and user experience. Over four months, Andrea reorganized statistical method topics within CSV files to clarify data structure, authored a reproducible Propensity Score Matching workflow guide in R Markdown, and linked datasets directly to documentation for streamlined analysis. Using R, Markdown, and Git-based workflows, Andrea enhanced onboarding and peer review by ensuring traceable, well-documented changes. Additionally, Andrea improved navigation by adding clickable GitHub profile links to contributor pages. The work demonstrated careful attention to data integrity, documentation quality, and maintainable engineering practices.
