Linux expert

Linux kernel and applications
Having ported Linux on different architectures I have a deep and up to date understanding of the Linux kernel and Systems On Chip. Mainstream reviewer for Linux IBM PCI.
Virtualisation
QEMU/KVM mainstream maintainer for IBM Cryptographic processors and developments for VIRTIO-CCW, VFIO-PCI, VFIO-AP and VSIE inside IBM research center.
Real time systems
My good knowledge of the SoC and Operating Systems provides me with good skills for the conception of deterministic architectures and applications.
Embedded systems
Several years of experience in resolving issues between hardware and software in embedded systems afford me a good knowledge of the ARM, Power, MIPS, IAPX and SH4 architectures.
