Bjorn Neergaard is a Senior Software Engineer with 14 years of experience building and hardening cloud-native infrastructure, tooling, and developer workflows. Currently at Docker, he combines backend systems work with DevOps and release automation, contributing to high-profile open-source projects like Moby, containerd, and python-poetry. His contributions span kernel-adjacent storage drivers, container runtime security, CI/CD portability (notably FreeBSD automation), and performance-minded refactors for editor tooling like ALE. Comfortable moving between Rust/Go/Python ecosystems, he’s equally at home diagnosing subtle system-level behaviors (metacopy, seccomp, AppArmor) as shipping cross-platform install and test automation. Colleagues describe him as a “software plumber” and hardware dabbler—someone who finds and fixes the plumbing others don’t see.
