Top SchoolErwan Velu is a seasoned technical leader and low-level engineer with 16+ years delivering Linux, hardware enablement and large-scale infra solutions, currently serving as President and Senior Staff DevOps Hardware Engineer at Criteo. He has led firmware/OS validation, performance analysis and lifecycle management for 50K+ bare-metal servers while interfacing with OEM/ODM R&D and level-3 support. A long-time open-source contributor and conference founder (Kernel Recipes, Premday, Embedded Recipes), he combines hands-on kernel and tooling work—authoring the Hardware Detection Tool and contributing performance improvements to the widely used fio project—with public speaking and mentoring. His background spans clustering and distributed storage pre-sales to building deployment and benchmarking frameworks at Red Hat, showing a rare mix of product, pre-sales and post-sales experience.
