About Me

Hi, I’m Will Paik.
I bridge the gap between High-Performance Computing (HPC) hardware and AI/ML models.

Currently, I work as an HPC Machine Learning Performance Engineer, optimizing large-scale infrastructure to train models faster and more efficiently. My goal is to make complex supercomputing environments accessible and productive for researchers and engineers.

CORE STACK: Slurm Linux Docker/Apptainer PyTorch Distributed Ansible

I run The Login Node, a tech channel dedicated to HPC Tutorials, System Optimization, and DevOps for Science.

My philosophy is simple: “If you can’t log in, you can’t compute.”
