Summary
🤩
Rockstar🎓
Top SchoolDavid Gibson is a Principal Software Engineer with 26 years of systems and open-source experience, currently at Red Hat where he leads development of passt and pasta for rootless network connectivity in containers and VMs. His deep kernel and virtualization expertise stems from long-term work on QEMU, KVM, Kata Containers and early Linux bring-up for new CPUs across PowerPC, embedded ARM and others. He is the author and maintainer of the device tree compiler (dtc), and his contributions to projects like RTEMS, ccan, Podman and Kata Containers show a focus on libfdt robustness, low-level safety fixes and practical testing/CI improvements. Comfortable across C, Rust and platform-specific QEMU plumbing, he blends low-level hardware enablement with pragmatic tooling that benefits developers and operators. Based in Canberra, he combines enterprise virtualization experience from IBM and Red Hat with a habit of fixing subtle undefined behavior and build / bring-up issues that often block platforms from shipping.
