Hey, I’m Gerard
Hey, I'm Gerard. I've spent 20+ years deep in IT — architecture, security, networking, infrastructure — working with companies all over the world and breaking plenty of things along the way so you don't have to.
These days I'm based in Dublin, where I make videos that cut through the noise on cybersecurity, networking, cloud security, and building your own homelab. My philosophy is simple: the best way to learn this stuff is to get your hands dirty, so that's what I try to help people do.
When I'm not buried in a homelab, you'll find me converting an old BT van into a campervan, chasing trails around Ireland, or staring at a mountain wondering if I've packed enough snacks.
If you've got a project, a collab idea, or just want to talk shop, give me a shout — I'd genuinely love to hear from you.
Tech with Gerard
On my YouTube tech channel, I focus on helping you grow your IT skills through both certification learning and hands-on lab experience. These videos are designed to guide you through key concepts, making complex topics easier to understand while also showing you how to build and experiment in your own lab environment.

On my other YouTube channel, I make videos about everything I do outside of Tech... vlogs, running, hiking, random travel adventures!
