Summary
🤩
Rockstar🎓
Top SchoolSean Dague is a seasoned software engineer and cloud architect with 20 years of experience, currently serving as Chief Cloud Architect for IBM Quantum. A long-time open source advocate, he has contributed to foundational projects across cloud (OpenStack), virtualization (Xen), clustering, storage (NFS Ganesha), and 3D internet (OpenSim), blending deep backend and DevOps expertise with robust testing and automation work. He’s known for improving reliability and developer workflows—examples include stabilizing Nova live-snapshotting, hardening DevStack installs, and modernizing OpenStack’s requirements and testing pipelines. Comfortable moving between database schema work, client libraries, and frontend UX tweaks, he combines physics training (Wesleyan) and an MS in Computer Science with a pragmatic, community-first approach to building sustainable ecosystems. Notably, his contributions often focus on the less-visible but high-impact plumbing—build tooling, test infra, and integration fixes—that keep large open source clouds running.
