PROFILE
Charlie Henry
Worked on the cityofaustin/vision-zero repository to develop and enhance ETL pipelines that integrate Moped project data with crash records, focusing on improving data quality and reliability for downstream analytics. Leveraged Python, Docker, and Geopandas to implement spatial joins, buffer project geometries, and refine data extraction through optimized GraphQL queries. Adjusted spatial buffering logic to use distinct distances for point and line geometries, enabling more accurate crash-to-component associations. Maintained reproducibility and build stability by updating dependencies and environment configurations. All changes were version-controlled with clear commit messages, supporting traceability and facilitating targeted safety analytics for urban transportation projects.
