Database Kernel Architect — Consulting Member of Technical Staff, Oracle
Redwood City, California
For the past seventeen years I've worked on the core of Database Kernel — operating-system internals, processors and memory, and how data moves between storage, network, and CPU. Lately my work has reached further up the stack: query processing, GPU offload for data-intensive and AI workloads, and the growing overlap of AI and databases. I like building the kind of low-level systems that quietly hold everything else up, and I write and speak about it at systems, storage, database, and security venues.
