Hi, I am JunHyun.

Azure MSP → Multi-Cloud In-House → Financial Sector Cloud — I am a Cloud Infrastructure/Security Engineer with 6 years of hands-on experience designing, building, and securing large-scale cloud environments.

Starting at an Azure MSP handling major game company clients, I moved in-house to a game company where I operated AWS, Azure, GCP, and Tencent simultaneously — building IaC pipelines with Terraform & Terragrunt, automating operations with Python, and managing FinOps across all CSPs. Security has been a consistent part of every role: from WAF, CSPM audits, and IAM design in multi-cloud environments to Zero Trust-based access control in enterprise financial infrastructure.

Throughout every role, my consistent strength has been turning repetitive manual work into automated workflows — reducing errors and giving teams the space to focus on what matters.

I believe infrastructure and security are not separate disciplines. They should be designed together from the ground up. My goal is to become an engineer who builds systems that are resilient, automated, and secure by design — not by afterthought.

안녕하세요, 김준현입니다.

Azure MSP부터 멀티클라우드 인하우스, 금융권 클라우드까지 6년간 클라우드 인프라 전 영역을 직접 설계하고 운영해온 엔지니어입니다.

Azure MSP에서 게임사 고객을 전담하며 시작해, 이후 게임사 인하우스에서 AWS·Azure·GCP·Tencent 4개 CSP를 동시에 운영하며 Terraform·Terragrunt 기반 IaC와 Python 자동화를 실무에 깊이 녹여냈습니다. 보안은 모든 경력에서 별도의 레이어가 아닌 인프라 설계의 일부로 다뤄왔습니다. WAF·CSPM·IAM 설계부터 금융권 Zero Trust 기반 접근 통제까지 직접 수행해왔으며, 반복되는 수동 작업을 발견할 때마다 자동화 코드로 전환해 팀이 본업에 집중할 수 있는 환경을 만드는 것이 제 일하는 방식이었습니다.

인프라와 보안은 처음부터 함께 설계되어야 한다고 믿습니다. 자동화와 보안이 내재된 인프라를 통해 시스템이 스스로 견고해지고, 팀 전체의 생산성이 높아지는 환경을 만드는 엔지니어가 되고자 합니다.
