Paul Cuzner
Software Architect at Red Hat
Auckland, Auckland, New Zealand
Summary
🤩
RockstarPaul Cuzner is a seasoned software architect with over 20 years in IT and 13 years focused on storage, data management, backup/recovery and virtualization, now shaping storage and cloud-native projects at IBM after a long tenure at Red Hat. He brings mainframe-honed principles—scalability, longevity, process and clear communication—to modern distributed storage design and operational tooling. A prolific open-source contributor, Paul has hands-on experience improving Ceph and Performance Co-Pilot, adding Ceph-volume features and device metadata integration and hardening PCP’s Gluster integration for stability under disruption. He combines architecture and field-facing roles—competitive analysis, partner demos, and technical documentation—with deep engineering craftsmanship in back-end and DevOps work. Colleagues rely on him to translate complex storage requirements into usable, automatable solutions (including REST APIs and Cockpit integrations) that reduce operational friction. Based in Auckland, he’s equally comfortable prototyping upstream projects on GitHub as he is driving large-scale storage roadmaps for enterprises.
