About Me

Welcome! I'm Sejong Kim and currently working as a software engineer from Seoul, South Korea.

I have a keen interest in Storage Systems, Distributed Systems, and Security. With a strong ability to self-learn, I enjoy grasping the whole picture of complex systems.

I derive satisfaction from finding optimal and creative solutions to current or future problems, collaborating with colleagues. I strive to apply techniques and designs from both technical and business perspectives.
