Senior GIS and photogrammetry specialist driving automation and accurate terrain modelling.
BulgariaWhat I'm looking for
I am a Senior GIS and photogrammetry specialist with seven years delivering geospatial projects across 21+ countries, including the US, UK, EU, and the Middle East. I specialize in drone data processing, DEM/DTM generation, spatial data automation, and large-scale quality control.
At TraceAir I processed over 100,000 drone images to produce 100+ DEMs and terrain models, delivering centimeter-level accuracy and actionable cut/fill analyses that improved earthmoving strategy. I optimize workflows and CRS alignment, and I focus on improving modeling accuracy through optimized GCP placement and TIN evaluation.
At Intetics | HERE I led automation and data-standardization efforts, developing 28 geodatabases and Python scripts that reduced processing time by up to 34% and cut cartographic production costs by 15%. I also designed customized QC processes that reduced error rates and supported team coordination and onboarding.
I mentor junior GIS staff, create process documentation, and collaborate cross-functionally to integrate geodata into product and client systems. I bring strong technical skills in ArcGIS Pro, ArcGIS Online, QGIS, Agisoft Metashape, Python, and PostgreSQL to deliver scalable, reliable mapping solutions.
