PROFILE
Henryglee
Henry Lee developed two core data engineering features for the BigData2025-Rev/p3 repository over a two-month period. He built a PySpark-based pipeline to consolidate state-level census data from multiple CSV sources, joining datasets on a common identifier and producing a headered output for downstream analytics. His work included detailed inline documentation to support maintainability and reproducibility, particularly clarifying the 2010 US Census workflow. In the following month, Henry delivered a population growth analysis tool using PySpark and Pandas, enabling decade-over-decade growth calculations for metropolitan and non-metropolitan districts and exporting results to CSV for further visualization and analysis.
