He discovered the world of open-source GIS in 2012 after arriving at his desk one morning to find that ArcGIS had still not finished his "clip" operation. Now an active member of the open-source GIS community, he is a core contributor to the PostGIS spatial database and GEOS geometry library, and occasional contributor to several other projects. He has lead and developed diverse projects, from buzzwordy stuff like a React-based distributed editing system using microservices, to low-level algorithms to generate polygon datasets from non-spatial source materials. Before focusing on software development, he worked in the field of environmental site remediation.
