Description

I help organizations manage and transform complex geospatial data into reliable, structured datasets for analysis and decision-making.

With 20+ years of experience in GIS and geospatial data processing, I specialize in data migration, integration, and quality control of large and heterogeneous datasets. I design efficient workflows and work extensively with PostgreSQL/PostGIS, QGIS, and spatial analysis methods.

I have worked on international projects (UNHCR, research institutions) involving large databases, historical maps, and remote sensing data. My focus is on delivering clean, consistent, and high-quality data that can be directly used in operational and analytical contexts.

Available for remote projects.
