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.

Global Ski Atlas
MapTiler, JavaScript, Python, ETL, Web GIS
Why it matters: Makes 3,000+ ski areas searchable on one live map, kept current by automated Python ETL instead of hand-edited data.
Vector Ledger
ArcGIS, Python, REST APIs, SQL Server
Why it matters: Bridges ArcGIS editing with lakehouse patterns (Iceberg, GeoParquet) so map updates are validated, versioned, and queryable.
Admin Boundary Tool
MapTiler, GeoJSON, Natural Earth, Web GIS
Why it matters: Turns a common cartography need into a reusable boundary workflow instead of manually clipping polygons every time.
MapTiler Agent Grader
MapTiler SDK, Web GIS, PMTiles, Agent eval
Why it matters: Grade agent MapTiler code against maptiler-skills.
Raiders of Antikythera
MapTiler SDK, PMTiles, GeoJSON, Game design
Why it matters: Proves serious geospatial data can power engaging experiences — real survey tracts, fog-of-war, and chapter-driven discovery.
Platform labs
Mapping and cloud playgrounds
Same hub pattern for each stack — why I use it, what I've built, and what's coming next.
