CURIOUS MIND.
CONNECTED THINKING.
I’m Tay Trinh Anh Dien Jordan. My focus is IT Infrastructure—understanding how devices communicate, how systems operate, and how to solve problems one step at a time.
I’m studying Higher Nitec in IT Systems & Networks at ITE College Central. I was admitted to the Director’s List for meritorious academic performance from April to September 2026.
My next step: turning classroom learning into clear, practical project documentation.
