GIS Specialist | ArcGIS - QGIS - GEE - GeoDa - Python

I’m a GIS Specialist with 4+ years of hands-on experience in spatial analysis, remote sensing, and environmental modeling. My work focuses on delivering high-quality GIS outputs that are not only technically correct but also easy to understand and ready for decision-making. I have worked on international projects, including soil map digitization for Germany, and supported academic research, environmental studies, and business-related spatial analysis. My expertise covers end-to-end GIS workflows — from data sourcing and cleaning to analysis, modeling, and final map production. Currently, I focus on spatial analysis related to environmental systems, hydrology, agriculture, and climate change, combining GIS tools with Python for deeper analysis and automation.
