About Me
Hey there. I'm Jonathan — a GIS developer with 15+ years building enterprise geospatial applications for CDC, utilities, and federal clients. I work in ArcGIS Enterprise, Python, JavaScript, and PostGIS, with a focus on web mapping, spatial databases, and automated ETL workflows.
Currently at DRT Strategies (CDC). Also building tools at Vector Scope AI. Previously National Grid, U.S. Census Bureau, C2 Solutions (Reston, VA), and Booz Allen Hamilton (FEMA/DHS).
