Wanhae is a member of CloudPlatform team at Kakao Corporation in South Korea. He is developing and maintaining private Kubernetes as a Service working on private IaaS in the company. He did quite a sort of things for that system, which included designing and developing an API server for the KaaS, user tools (web, terraform provider, and cli) for that API, and controllers (or operators) for users if necessary. He is interested in making the cloud more accessible and friendlier to users so that users can focus on their domain, not the cloud.
