Top SchoolAshok Raj is a Principal Engineer and platform architect with 26 years of experience designing resilient Linux and virtualization infrastructure, currently based in Portland and leading Linux work at Qualcomm after a long tenure at Intel. He has repeatedly turned research into production, from pioneering VT-d and I/O virtualization to driving live microcode updates and in-field CPU scan technology that raised cloud-scale availability. Known for cross-functional HW/SW co-design, Ashok led industry-impacting initiatives like Machine Check Architecture and Posted Interrupts that delivered measurable performance and reliability gains. A prolific innovator with 45+ granted patents, he combines deep kernel-level expertise with standards knowledge across PCIe, CXL, ACPI and UEFI. As a founder and mentor he builds teams that translate strategic vision into production-ready systems, often aligning firmware, kernel, and silicon stakeholders to ship at scale. Less obvious: his career includes early cross-platform device efforts—shipping the first InfiniBand implementation that reused common source across Linux, Windows, VxWorks and UEFI—demonstrating a long-standing emphasis on portable, maintainable system software.
