About

I'm Justin. I make things, grow things, and pull things apart to understand how they work.

This site is a workshop notebook for four habits that keep overlapping. The builds come off a shelf of FDM printers, and run to functional parts, jigs, and the occasional thing that started as a photo. The garden is hydroponics: growing food without soil and learning the chemistry the hard way. The lab is the home network and the boxes that run on it, the place I get to break real infrastructure safely. And the writeups are security walkthroughs from hands-on practice, the thread that ties the rest together.

The pattern is always the same: pick something up to learn one thing, then keep doing it because it's satisfying. A print becomes a print farm; a single resolver becomes a whole network; a practice box becomes a habit of asking "how would this actually break?" The security work is where the curiosity gets sharpest: figuring out how a system fails, then writing down how you'd stop it.

Most of what's here is mid-progress, and that's deliberate. If any of it is useful to you, that's a bonus.

Off the clock I build, grow, and break things. On the clock it's the same instinct at a much larger scale: I lead cybersecurity for a large, privately held multinational, where I'm accountable for the global program (security architecture, governance and risk, compliance, and operations) across tens of thousands of people in more than a dozen countries. It's a heavy, operational business whose roots are in industry rather than IT, which is what makes the work interesting. The hard part is less the tooling and more shipping controls a round-the-clock operation can actually live with, while still standing up to the auditors, insurers, and regulators who get a say in whether they're good enough.

The home lab and the writeups here are that same instinct with the stakes turned down: run real systems, watch how they actually fail, and write down what I learned so I don't relearn it the hard way. The Proxmox cluster, the firewall pair, the monitoring stack. None of it is production for anyone but me, which is why it's a safe place to break things deliberately. The formal version of all this lives on the CV; this page is the part I'd rather talk about at a workbench.

One note, since the day job comes up: this is a personal site, written in a personal capacity. The opinions, projects, and writing here are my own, not my employer's, and none of it draws on confidential or privileged work or describes any employer's systems.
