Summary
Jangjae Lee is a Platform Engineer and cloud-native DevOps leader based in Seoul with nine years of focused experience and over 15 years total in systems and Linux engineering. He has led cloud migration and platform teams, designing AWS and GCP multi-account landing zones, multi-cluster Kubernetes architectures (EKS/GKE/RKE) and IaC with Terraform while acting as Cloud DevOps Team Leader and Cloud Migration PM. Comfortable across CI/CD (GitLab CI, GitHub Actions, Argo family, Spinnaker), observability (Prometheus, Grafana, CloudWatch, GCP Logging) and service mesh evaluations (Istio, Linkerd), he pairs hands-on troubleshooting—using strace/ltrace/ftrace and increasingly eBPF—with strategic platform decisions. Known for pragmatic PoC-driven recommendations and building onboarding programs, he also contributes technical writing on his blog and maintains a public GitHub presence. Colleagues rely on his strong communication and leadership to deliver secure, reliable cloud-native services from on-prem migrations to production-grade Kubernetes platforms.
