Ivan Arias

GIS Analyst · Geospatial data & Web GIS

I spent thirteen years mapping what lies underground for PDVSA in Venezuela and Ecuador. Since 2022 I've been bringing that work to the web, building maps and spatial tools with Python, PostGIS and Leaflet.

Now in Den Haag and looking for GIS analyst and Web GIS roles. Say hello.
