Doyeon Guk

Hi! I’m Doyeon Guk — an ICT Trainer, Database Administrator, and Cybersecurity Specialist based in Melbourne, Australia.
I hold a Bachelor’s in Software Engineering from the University of Melbourne. I currently teach Advanced Diploma of IT units at Danford College, where I combine academic expertise with hands-on industry experience to support students in cybersecurity, network systems, project management, and database design.
In between code and lectures, I’m also building solutions that connect people — like a digital membership system for the Korean Association.
When I’m not coding or teaching, you can find me exploring Melbourne’s vibrant tech scene, enjoying a good book, or sharing insights on my blog. Let’s connect and make the digital world a safer, more accessible place!
