United States

Message

I support environmental and construction projects with ArcGIS Pro, mapping species occurrences, ground-cover change, coastal dredging areas, and project buffers for the U.S. Army Corps of Engineers.

My work combines aerial imagery, municipal GIS data, field surveys, and environmental compliance documentation to produce useful project records and planning outputs.

At the Natural History Museum of Los Angeles County, I led research on introduced terrestrial snail distribution and ecology across Southern California, using iNaturalist records, field data, Excel, and georeferenced observations.

I'm completing a GIS certificate and building Python workflows for habitat modeling, LiDAR and raster processing, terrain analysis, CART classification, and k-means clustering using PDAL, GDAL, and Rasterio.
