Back to original languageAbout Kadjo Raphael
Passionate about spatial analysis, mapping, and geographic data management, I hold a PhD in Geography and design GIS tools and natural risk models that combine geomatics, machine learning, and agent-based simulation. I am proficient in ArcGIS, QGIS, Python, and R for data analysis, process automation, and satellite imagery exploitation.
As part of a CIFRE thesis conducted with SDIS 95, I developed operational risk and vulnerability indices that helped reduce intervention times by 17.5% and the number of exposed individuals by 23% during crisis situations.
Versatile, rigorous, and problem-solving oriented, I am available to support consulting projects, risk mapping, spatial modeling, and geographic analysis, both in France and internationally.
