Summary
🤩
Rockstar🎓
Top SchoolRaymond Nijssen is a seasoned GIS specialist with 15+ years applying open-source geospatial technologies like QGIS, PostGIS, GeoServer and OpenLayers to real-world mapping and modeling projects. As founder of Terglobo and coordinator roles in Dutch GIS cooperatives, he blends hands-on Python and SQL development (GDAL/OGR, QGIS plugins) with cartographic craft and training. He contributes to core QGIS development and documentation—adding geometry algorithms and improving website localization—showing both deep technical skill and attention to user experience. His background spans government and private sector GIS coordination, giving him a pragmatic understanding of spatial data governance and project delivery. Based in ’s-Hertogenbosch, he leverages Blender 3D and traditional ESRI toolsets where needed, making him comfortable across the open and proprietary GIS ecosystems. Colleagues rely on him for practical geographic modeling solutions that balance algorithmic rigor with clear cartographic communication.
