Sangyeon Lee:

I design, build, and care for reliable compute infrastructure: from HPC clusters (Slurm, MPI, InfiniBand) to Kubernetes platforms and secure Linux servers. I like turning messy systems into fast, well-documented, and automated ones.

About

Junior Computer Science – Information Technology major focused on systems and infrastructure. I've worked as an HPC Cluster Technician and Student Information Technician, supporting cluster expansion, job scheduling, and end-user workflows. I document thoroughly and prefer scripts for repeatability.
