About Me
I'm Jonathan, a Solutions Architect–track GIS engineer with 15+ years designing cloud and enterprise geospatial systems for CDC, utilities, and federal agencies. I pick ArcGIS, AWS, and spatial data pipelines based on what the system needs to run reliably.
Currently Geospatial Engineer at INCATech, on U.S. Postal Inspection Service (USPIS) work. Previously a CDC Geographer (federal employee, then DRT Strategies contractor), National Grid, the U.S. Census Bureau, C2 Solutions, and Booz Allen Hamilton (DHS). Studying for AWS Solutions Architect – Associate. On the side I run Vector Scope AI, a collaborative map editing product with approvals and a versioned GeoParquet lake on AWS.
Core Skills
AWS
ArcGIS Enterprise
Python
PostgreSQL/PostGIS
System Design
REST APIs
JavaScript / React
ETL Automation
GeoParquet / PMTiles
CI/CD
Cloud work
AWS and cloud architecture — serverless backends, edge delivery, and systems you can click.
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.
Learn Bosnian
S3, CloudFront, Lambda, API Gateway, DynamoDB
Why it matters: Learners tap vocab and dialogue to play voice-overs; talent records from a password-gated studio that uploads clips to S3 for CloudFront playback.
Side projects
Maps, tools, and experiments — GIS craft without the cloud architecture case study.
Nepal Census Atlas 2011
Story-driven choropleth atlas from Nepal’s 2011 census — place narrative over color ramps.
Choropleth · GADM · Narrative cartography
BuildingPop (OSM)
Draw an area, pull OSM buildings via Overpass, estimate population vs WorldPop / GHS-POP.
OpenStreetMap · Overpass · Leaflet
Admin Boundary Tool
Punch any state or province out of a country polygon for map highlights.
MapTiler · GeoJSON · Natural Earth
Raiders of Antikythera
Dig game on real Antikythera Survey Project tracts — fog-of-war GeoJSON, PMTiles finds.
MapTiler SDK · PMTiles · Game design
Map Agent Arena
Compare Mapbox / MapTiler agent skill packs in a dedicated eval arena.
Mapbox GL JS · MapTiler SDK · Agent eval
Platform labs
Mapping and cloud playgrounds
Each link opens a short write-up: when I pick that platform, what I've built with it, and what is still in progress.
