Geospatial developer and aerial photographer specialized in photogrammetry, cadastral systems, and artificial intelligence for land surveying. With a strong background in GIS, drone technology, and Python development, I create innovative solutions that bridge the gap between technology and real-world geospatial challenges.

Co-creator of TipologIA - Colombia's first AI-powered cadastral recognition system, fully compliant with the LADM-COL standard.

Currently building SkyMapStories - capturing stunning aerial perspectives and providing professional topographic services with drones.
