Senior🎓
Top SchoolStefan Lasiewski is a seasoned computer systems engineer with 12+ years designing and running production infrastructure for research and enterprise environments, currently leading the Spin container platform at NERSC/LBNL. He architects Kubernetes- and Rancher-based solutions that enable scientists and ML practitioners to deploy containerized services reliably, and has authored over 200 pages of internal documentation and training to operationalize those choices. Comfortable across Unix variants (Linux, FreeBSD, Solaris) and services from Apache to MySQL and Docker, he has a long track record of improving uptime, automation, and performance in 24x7 operations. Based in Berkeley, he blends deep systems-level knowledge with a knack for translating complex infrastructure decisions into clear guides and hands-on user training—helping teams adopt cloud-native tooling without losing sight of high-availability requirements.
