Summary
🤩
Rockstar🎓
Top SchoolIan Wienand is a senior software engineer with 22 years of experience specializing in kernel and systems programming, cloud infrastructure, and CI/CD for large-scale production environments. Currently in Linux Kernel Sustaining Engineering at Red Hat, he previously spent a decade building and operating OpenStack services and tooling, contributing to projects like openstacksdk, neutron, devstack and diskimage-builder. He blends low-level C and computer architecture expertise with practical automation skills (Ansible, containers, Zuul, GitLab) and a strong track record in packaging, deployment and debugging production issues. A long-time Debian developer and active open-source maintainer, his contributions range from improving pip and pytest-testinfra to hardening OpenStack DHCP and storage workflows. Colleagues rely on him for fixing subtle race conditions and diagnostic gaps—work that often surfaces as better logging, tests and deployment resilience. Based in Melbourne, he pairs research-rooted rigor (UNSW MEng) with hands-on operational pragmatism across cloud and kernel domains.
