Server Developer & Machine Learning Engineer

소개

새로운 기술을 배우는 것을 좋아하는 개발자입니다. 한 분야를 깊게 파는 Specialist라기 보다는 여러 분야 기술을 잘 융합하여 필요한 곳에 적용하는 Generalist에 가깝습니다. 조직 내 필요로 하는 분야에 대해서 빠르게 배워서 일을 진행하는데 능숙합니다.

현재 관심사는 SRE (Site Reliability Engineering) 및 DevOps 등 Server-side Infrastructure Engineering에 관심이 많습니다.

요즘은 주로 Ruby on Rails (EKS) + MySQL (AuroraDB) 와 React + MobX state tree (static S3) 로 Web Application 개발을 하고 있습니다.
