Summary
👤
Senior🎓
Top SchoolWanhae Lee is a cloud-native software engineer with a decade of experience building and operating large-scale Kubernetes platforms and developer tooling, most recently contributing at LINE Plus and previously managing 1000+ clusters at Kakao. He excels in Golang, Kubernetes internals (CRI/CNI/CPI), Linux networking and eBPF troubleshooting, and has a knack for rapid incident recovery—once restoring a container registry for 7K+ clusters within an hour during a datacenter blackout. As an instructor of an advanced Kubernetes deep-dive, he distills complex controller patterns and networking behaviors for SREs while continuing to explore emerging topics like Wasm for serverless, CockroachDB consistency nuances, and single-developer Kubernetes projects. His background spans on-call automation, private-cloud Kubernetes-as-a-service, and hands-on systems work from military C4I servers to research and product roles, reflecting a pragmatic blend of operational rigor and curiosity-driven experimentation.
