Rockstar🎓
Top SchoolBrad Lewis is a senior software engineer with 9 years of recent experience and a long track record (dating back to the 1990s) building high-performance storage, parallel algorithms, and kernel-level features. He has driven substantial ZFS improvements—authoring a patented parallel intent-log execution model and contributing ARC reclaim fixes to OpenZFS—while leading analytics and telemetry subsystems at Delphix. Comfortable across C, kernel modules, Java backends, and Python/BCC tooling, he bridges low-level systems work with service-oriented APIs and monitoring. An inventor on seven patents, Brad has repeatedly turned deep performance analysis into production gains and reduced integration defects through improved testing and developer training. Based in Loveland, Colorado, he brings a rare combination of HPC numerical optimization experience and practical cloud/observability engineering that helps teams diagnose and fix real-world performance issues.
