Hyuntae Yoo (Hunter)
Cybersecurity & Network Engineering student focused on real-world infrastructure and security.
I design, build, and document secure network infrastructures.
About
What I do
I build network and security lab environments, document implementations step-by-step, and validate results with repeatable checks. My portfolio is structured to showcase outcomes quickly while preserving the technical depth engineers expect.
How this site is organized
Courses show formal training and key outcomes. Projects highlight major builds end-to-end. Documentation contains step-by-step writeups (procedures, commands, verification, and troubleshooting).
