| 🦠 | Global Polio Surveillance Pipeline | Production ETL pipeline for WHO/IMB across 79 countries. Invented a Spatial Binning method to fix a root data quality problem — one-size-fits-all metrics were hiding virus circulation in small provinces. Added 4 automated surveillance flags. Maintained on GitLab for 2 years. Published Vaccine X 2020. | R · SQL · WHO POLIS · WorldPop · GitLab | Code · Paper |
| 💛 | Donor Revenue Analysis — Chance Center | Integrated 3 disconnected data sources (Donorbox, Luma, Excel) in R. Deduplicated donor identities, tracked payment history and tenure across records. Finding: only ~100 active donors. Directly drove new registration policy + membership survey. | R · Data Integration · Excel | Case Study |
| 🏀 | NBA × WNBA PER Dashboard | Built an interactive Shiny app comparing Player Efficiency Ratings across leagues. No public WNBA dataset existed — hand-scraped player data from Wikipedia + scripted Basketball-Reference.com. Presented at R-Ladies Atlanta × Atlanta Hawks. | R Shiny · ggplot2 · tidyverse · Web Scraping | Code · Demo |
