Geospatial engineer at Telespazio Ibérica automating quality checks for 1:1,000 urban mapping with Python and ArcPy.

At Telespazio Ibérica, I use Python, ArcPy, GDAL and ArcGIS Pro to automate geoprocessing and QA/QC for 1:1,000 urban mapping. I write scripts to validate geometries and attributes, check topology and produce quality-control reports.

At SRM / Ipsilum, I maintained geospatial databases and contributed to transport-network updates and BTN/BTN25 cartographic production. Earlier, at Visual50 S.L., I developed a Web GIS application with Python and Flask, backed by a SpatiaLite database.
