Rockstar🎓
Top SchoolIan Milligan is a software engineer with 12 years of experience building backend and infrastructure for cloud-native systems, currently at Google and based in Maple Valley, Washington. He has deep expertise in Kubernetes-focused projects, contributing to high-profile open-source efforts like Knative Serving and Eventing where he improved build systems, tracing, and event dispatch reliability. His work on the CloudEvents Go SDK and Knative packages highlights a strong focus on observability, transport abstractions, and race/memory-safety fixes that improve production robustness. Prior roles include backend engineering at Basho Technologies, and he holds a BS in Electrical and Computer Engineering from Oregon State University. Colleagues know him for pragmatic refactors—such as replacing envsubst with Bazel template expansion—and for quietly fixing subtle concurrency and memory issues that surface only under real-world load.
