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.
Systems & administration
The operating systems, users and services that keep an environment working.
Practical problem-solving
Break a problem down. Test an idea. Understand why a solution works.

BIGGER POSSIBILITIES.
Live projects first. A closer look when you want it.
LIVE DEMORead PING-BOT project details
A fictional campus with six connected spaces and five support stories. Explore from first-person or robot view, investigate symptoms, and check that each repair helped the person who needed support.
- 01 / LISTEN
Start with the person.
Meet Amina, whose classroom cannot reach its learning portal. Ask who is affected, understand what still works, and protect their saved projects.
- 02 / INVESTIGATE
Follow the evidence.
Trace links, addressing, VLANs, DNS and Wi-Fi through simulated commands and hints before attempting a repair.
- 03 / VERIFY
Make the fix count.
Run verification, then check back with the person. The story is complete when they confirm they can get back to work.
LIVE DEMO
PACKETQUEST
02 / LIVE PROJECTA retro learning adventure. Restore NeoGrid through gateway, routing, DNS and simulated Linux challenges.
Read PacketQuest project details
Play as Router-01 in a fictional network kingdom. Follow the gold route, work through networking challenges and reconnect NeoGrid, one encounter at a time.
- 01 / EXPLORE
Follow the gold path.
Move through a pixel-art world using keyboard controls or a mobile direction pad. Each encounter introduces the next network problem.
- 02 / LEARN
Turn concepts into choices.
Practise default gateways, static routing and DNS with questions, explanations, hints and retries.
- 03 / REPAIR
Take on the terminal.
The Debian boss introduces typed Linux commands in a safe simulation. No real system commands are executed.
NEXT ON
THE WORKBENCH.
Directions for my next practical projects. These lab concepts are planned work, not completed projects.
What I’ll document: the setup and topology, configuration screenshots, test results, problems encountered and how I solved them. Completed evidence will be added as each lab is built.
