Rockstar🎓
Top SchoolJakob Naucke is a software engineer with 7 years of experience specializing in Kubernetes, Linux, trusted/confidential computing, and DevOps, currently at Red Hat after a multi-year tenure in IBM’s Linux on Z and container teams. He contributes to high-profile open-source projects like Kata Containers, where he implemented s390x and VFIO-AP device pass-through, enabled virtio-fs, and improved CI/CD across architectures—work that bridges low-level system code and cloud-native tooling. Jakob’s background includes hands-on kernel and QEMU adjustments, packaging for s390x, and automating complex cross-architecture builds, reflecting deep expertise in mainframe-class hardware and secure virtualization. Based in Utrecht, he combines academic training from Delft and hands-on industry experience to solve platform-level reliability and compatibility challenges that are easy to overlook but critical at scale.

Contributions summary:Jakob primarily contributed to the Kata Containers project by implementing and supporting VFIO-AP (IBM Adjunct Processor) device pass-through. This involved adding support for hot-plugging IBM VFIO-AP devices, re-vendoring GoVMM, and enabling virtio-fs on s390x, a process which included modifications to the QEMU code and agent. Furthermore, the user addressed build and packaging issues related to s390x, including kernel installation and Dockerfile generation, while ensuring the agent supported CCW devices correctly. The contributions demonstrate a focus on supporting confidential computing technologies and s390x architecture.
