> whoami Name: Kim JunHyun (김준현 · Hann) Role: Public Cloud Infrastructure & Security Engineer Since: 2020~ Direction: I turn infrastructure and security that relied on people's memory into structures that code protects. From live games to financial services, running infrastructure across 4 clouds (AWS, GCP, Azure, and Tencent), at up to 3,500 servers and 650 databases. I have experience cutting deployment time by 40% by moving to Terragrunt and raising CSPM (cloud security posture checks) remediation from 60% to 85% or higher. - Feb 2026 – Oct 2026 Woori FIS · Information Security Department · Assistant Manager · Cloud Security Engineer- Feb 2023 – Feb 2026 Com2us Platform · Infrastructure Technology Office, Cloud Division · Assistant Manager · Cloud Engineer- Aug 2020 – Feb 2023 C&Thoth · Cloud Service Team · Associate to Assistant Manager · Cloud Engineer (Azure MSP) Principles from the field· Before adding a tool, see what the logs you already have can do.· Without authority, "I tried this and it got better" persuades more than "we should do this".· Stop at "no" and the conversation ends. Bring an alternative and things get fixed.· When you move clouds, make the security standard move with you.· Put the rule in structure and code, and every deployment meets the same bar.· Turning a control on is different from proving it stops the threat.· The requested fix ("please open it") and the real problem can differ. Check what is failing first.· AI supports the judgment. A person approves the action.
