Earth-Science Data Tooling — Packaged Scientific Python
Project
I developed scientific-data tools through NASA internships and UMBC research, including conversion to netCDF4 and parsing into pandas DataFrames. cosmic-crunch and noaa-gml-file-reader are published on PyPI; I also contributed to collaborative cloud-anomaly analysis.
Service Operations Map
Project
I turned a septic-services business’s customer spreadsheet into a touchscreen map with pricing zones, service-due heatmaps, and upsell flags. The shop adopted it in place of its sticker wall map.
