Beumjin Cho


I am Beumjin Cho, a senior cloud security engineer at SAMSUNG SDS Research.

I was a research and engineering manager (as a founder) at Warever, a startup.
I developed a API gateway platform designed for MSA, providing scalability, reliability, and security.

Prior to joining Warever, I received my Ph.D. from POSTECH under the supervision of Prof. Jong Kim.
My research was focused on security and data management in mobile systems and IoT.

Based on my experience, I have a deep interest in the modern computing technologies, such as highly scalable, available, and secure systems.
