I'm Doyoon Kim, a Cloud & Infrastructure Engineer focused on building reliable systems in distributed and production environments.

I enjoy understanding how systems behave under real conditions — not just making them work, but making them scalable, resilient, and operationally reliable.

I care about scalability, reliability, and real operational impact.
