Top SchoolQuentin Casasnovas is a Hypervisor & Kernel Engineer with 17 years of experience specializing in Linux kernel development, live patching, and low-level system architecture. He has led and built distributed teams at Oracle, architected kernel and DKMS build/CI pipelines at FlexAI, and now contributes to virtualization stack work at Vates/XCP-ng, bridging kernel internals with real-world deployments. Quentin combines deep expertise in security patching (Ksplice), assembler-level fixes across architectures, and hands-on work with GPUs, SoC architects, and micro-electronics to deliver pragmatic low-level solutions. He’s equally comfortable mentoring engineers, designing developer-facing tooling, and creating fast CI systems that produce kernel packages in minutes. Known for finding subtle vulnerabilities and porting advanced fuzzing tools into kernel workflows, he thrives in multidisciplinary, cross-cultural teams that tackle hard systems problems.
