About:

Backend & Infrastructure Engineer

Embracing the philosophy "Everything fails, all the time," I engineer systems designed for resilience. In the 'Buzz Book' project, I architected a Microservices Architecture utilizing RabbitMQ to ensure reliable coupon issuance under high traffic, effectively eliminating Single Points of Failure (SPOF). Furthermore, through the 'Linky' autonomous robot project, I established a GitOps workflow with ArgoCD and Kubernetes, creating a self-healing infrastructure that automatically recovers from deployment failures. My goal is to build architectures that ensure business continuity by preemptively addressing potential failures.

"모든 시스템은 결국 실패한다(Everything fails). 그렇기에 저는 실패해도 멈추지 않는 시스템을 설계합니다." 'Buzz Book' 프로젝트에서 RabbitMQ를 활용한 이벤트 기반 MSA를 구축하여 대규모 트래픽 상황에서도 안정적인 쿠폰 발급을 보장하고, 단일 실패 지점(SPOF)을 제거하여 시스템의 신뢰성을 높였습니다. 또한 'Linky' 자율 주행 로봇 프로젝트에서는 Kubernetes와 ArgoCD를 도입하여 자가 치유(Self-healing)가 가능한 GitOps 인프라를 설계했습니다. 장애가 발생하지 않기를 기도하는 것이 아니라, 언제든 복구 가능한 견고한 아키텍처를 통해 비즈니스의 연속성을 지키는 엔지니어가 되고자 합니다.
