Justin Curtis
Hey, I’m Justin — the guy behind JAC TechKnowledge-y.
Why the name? Those are my initials, and it’s a play on tech + knowledge. This channel is part of my personal web portfolio and a creative outlet for sharing what I learn.
From 2022 to 2024, I was stuck in the book-and-tutorial loop — always studying, rarely applying. In late 2024, I started building home labs, breaking things, fixing them, and learning by doing.
So I thought: why not document it?
I’m not a pro, and I don’t offer technical advice. I just share what I try, what works, what doesn’t, and what I learn along the way.
🎵 Music comes from my old Epidemic Sound subscription or Pixabay (royalty-free). All credit goes to the artists.
🖼️ Thumbnails are made using Canva + ChatGPT.
🎥 Videos are recorded on Linux, macOS, Windows, or iPhone — with audio from a Yeti Orb or Apple headset mic.
If you’re into practical, messy, real-world learning — welcome.
