About Me

GIS Developer with 14+ years of experience specializing in fullstack GIS development, 3D city digital twin solutions, and geodata management. Currently working at Haninge kommun, I develop cutting-edge geospatial applications that serve citizens and support democratic participation in urban planning.

My expertise spans from GIS system management and geodata infrastructure to advanced 3D visualization using Cesium, Unreal Engine, and modern web frameworks. I'm passionate about creating accessible, user-friendly solutions that make geospatial information available to everyone—from children finding playgrounds to citizens engaging in comprehensive municipal planning.

Throughout my career, I've focused on democratizing access to geographic information, ensuring that GIS systems serve not just professionals but all community members, contributing to transparency, participation, and improved quality of life.
