Jimmy Zelinskie is a co-founder and seasoned engineering leader with 14 years of experience building cloud-native infrastructure, developer tooling, and backend systems from San Francisco. He combines hands-on Go systems programming—contributions to projects like CoreOS Torus, Clair, and the Google Zanzibar-inspired SpiceDB—with product leadership at CoreOS and Red Hat where he helped shape OpenShift and operator lifecycle tooling. Jimmy has a strong DevOps pedigree, having improved CI/CD, metrics, and container security in projects such as Quay and operator-framework, and he still contributes to widely used open-source projects. A YC alum and Penn State information systems graduate, he’s as comfortable refactoring low-level storage and FUSE integrations as he is defining CRDs and install strategies, reflecting a rare blend of deep engineering craft and product-level impact.
