PROFILE
Henryglee
Over a two-month period, contributed to the BigData2025-Rev/p3 repository by developing two PySpark-based data engineering features focused on US census data. Built a state data consolidation script that reads and joins multiple CSV files on a common identifier, producing a consolidated dataset ready for downstream analytics. Enhanced maintainability through comprehensive inline documentation and clarified the 2010 census workflow for reproducibility. Delivered a population growth analysis tool that computes decade-over-decade growth rates for metropolitan and non-metropolitan districts, exporting results to CSV for visualization. Demonstrated strong proficiency in Python, PySpark, and data processing, establishing reproducible analytics pipelines without reported bugs.
