Summary

Senior🎓
Top SchoolDennis Follensbee is a senior software engineer with two decades of experience specializing in GIS data automation, PostGIS database management, and cloud-based data pipelines. Based in Lisbon, New Hampshire, he architects and maintains Python and Java tooling to produce quarterly GIS products at Precisely, pairing spatial libraries like Fiona and Shapely with AWS, Docker, and CI/CD practices. His career blends startup agility and enterprise rigor—from building navigation and geocoding systems at BroadMap and TomTom to hardening data quality processes at Tele Atlas—so he reliably turns messy spatial data into production-ready assets. An outdoorsman and expert in wilderness navigation, he applies the same meticulous map-and-compass approach to debugging complex geospatial workflows, making him especially adept at offline data recovery and satellite-imagery driven feature discovery.
