Top SchoolHansuk Hong is a backend and DevOps engineer with 9 years of experience building and operating production cloud platforms from Seoul. He has led platform and SRE work across on-prem and multi-region AWS environments, managing 10+ EKS clusters, reducing EC2 costs via Karpenter, and delivering sizable storage and query optimizations for data lakehouse workloads. At CREMA he combined software and ops skills—containerizing legacy Rails, orchestrating large-scale data syncs, and implementing CI and DB failover practices that materially improved availability and developer velocity. He designs gitops-driven cluster bootstrapping and infrastructure-as-code patterns, and teaches Kubernetes fundamentals through VOD content for certification candidates. Pragmatic about human roles in engineering, he emphasizes automating toil so engineers can focus on higher-value problems. Colleagues can expect a systems-minded operator who pairs backend development experience with platform-level cost and reliability wins.
