Summary
👤
Senior🎓
Top SchoolTim Hollingshead is a Software Development Engineer II with 11 years of professional experience and deep expertise in geospatial systems, particularly the ArcGIS platform. He has architected and delivered production-grade, full-stack geospatial applications and big-data image-processing pipelines—most notably systems that handled hundreds of thousands to over a million aerial images for FEMA disaster response. Comfortable across frontend React apps, Node.js APIs, and AWS serverless architectures, he blends solution architecture with hands-on implementation and has led customer-facing, mission-critical integrations in highly secure environments. Tim also built automated provisioning and CI/CD tooling at scale (SCIM provisioning for 16k+ accounts, multi-repo build pipelines), and mentors junior engineers to raise delivery quality. Based in Broomfield, Colorado, he pairs practical field experience (early Hadoop/MapReduce and construction work) with a software engineering degree from Rose-Hulman to solve complex geospatial problems.
