About Me

Hey there. I'm Jonathan — Founder & Principal at Vector Scope AI, delivering spatial intelligence solutions for government and enterprise. I build the lakehouse layer for ArcGIS: versioned GeoParquet and Iceberg, validation APIs, and collaborative editing so agencies keep analytics-ready data.

Previously at DRT Strategies (CDC), National Grid, U.S. Census Bureau, and Booz Allen Hamilton.

  • Designing Ledger Editor, Dashboard, Lake (GeoParquet storage), and Ledger Grid (Kubernetes GIS) with changelog history and validation APIs for agency pilots
  • Implementing rules engine and topology validation (e.g., pipe sizing) stored in lakehouse Parquet—enforce edit-time constraints without separate databases
  • Running Global Ski Atlas as live demo (3000+ resorts, web editor, public atlas) to prove the platform for boundaries and program areas
  • Pursuing Esri Startup Program and pilot engagements for agencies needing collaborative editing and GeoParquet for ArcGIS
