About Me
I'm Jonathan, a GIS engineer building toward Solutions Architect roles, with 15+ years designing enterprise geospatial systems for CDC, utilities, and federal clients. I connect ArcGIS, cloud platforms, and spatial data pipelines so maps and services scale.
Currently Geospatial Engineer at INCATech. Previously DRT Strategies (CDC), National Grid, U.S. Census Bureau, C2 Solutions, and Booz Allen Hamilton (FEMA/DHS). Studying for AWS Solutions Architect – Associate; also shipping tools at Vector Scope AI.
Core Skills
AWS
ArcGIS Enterprise
Python
PostgreSQL/PostGIS
System Design
REST APIs
JavaScript / React
ETL Automation
GeoParquet / PMTiles
CI/CD
Featured work
Download Resume
Global Ski Atlas
AWS, Step Functions, Lambda, DynamoDB, Python ETL
Why it matters: Production serverless GIS backend keeps 3,000+ ski areas current via automated ETL instead of hand-edited layers.
Vector Ledger
ArcGIS, AWS, Iceberg, GeoParquet, REST APIs
Why it matters: Map updates become validated, versioned, and queryable across Iceberg, GeoParquet, and changelog history.
Cloud Resume Challenge
S3, CloudFront, Lambda, DynamoDB, SAM, CI/CD
Why it matters: End-to-end cloud architecture you can click: static edge frontend plus a live visitor-counter API.
