I specialize in cartography, web mapping, spatial data analysis and management, and photogrammetry. Having worked both in academia and business, prestigious university and start-up, I have experience in studying and analyzing data in-depth, as well as establishing and automating a GIS workflow from field to client. Maps convert data to information, and I strive to use them to tell the best story possible. Software knowledge and skills: - ArcGIS Pro (georeferencing, model-building, spatial analysis, light python scripting) - ArcGIS Online (web mapping, dashboard, story maps, administration) - ESRI Field Maps and Survey 123 - Pix4D (RGB, thermal and multispectral imagery processing)
