Senior🎓
Top SchoolDuncan Mcgreggor is a veteran technology leader and current CTO with over four decades in computing and more than 15 years focused on networked and distributed systems. He blends hands-on engineering—shipping systems in Rust, Go, Clojure, Erlang/LFE and more—with strategic leadership of engineering organizations, having scaled teams and driven product and architecture at companies from Canonical and Rackspace to NASA contracts and startups. His work emphasizes resilient, realtime distributed services, cloud-native deployments, and open source community building, including long-term contributions to Lisp Flavoured Erlang and other OSS projects. Known for mentoring engineers and building engineering cultures, he has a track record of translating scientific and geospatial requirements into production systems (notably for NASA and USGS). Based in the Twin Cities, he also brings unusual depth from earlier roles in cryptologic/intelligence and formal studies in physics, mathematics and meditation, which inform his systems thinking and leadership style. Recent activity includes leading Banyan through acquisition by Bilt while continuing to contribute to language and community tooling.
