Welcome to Retr0's Lab

Hey. I’m retr0.

This is my lab. It’s where I put things—experiments, projects, ideas that don’t have a home anywhere else. If you’re here, you probably care about how things work. That’s good. So do I.

I’m a Site Reliability Engineer by trade. Most of my time goes into making systems predictable. Quiet. Resilient. The kind of infrastructure that doesn’t page you at 3 AM unless something actually matters. When things break, I want them to fail loudly, explain themselves, and leave fewer mysteries next time.

But here’s the thing—I also spend a lot of time with old machines. Commodore 64s. Classic Macs. Apple IIs. IBM PCs running DOS. Mainframes, when I can get my hands on them. There’s something about vintage hardware that teaches you things modern systems try to hide. Constraints force clarity.

What I Work With

I’m a generalist. Python is my main language. Solid background in C and C++. Learning Rust and Lua. I’ll write BASIC if the hardware demands it.

For infrastructure—Ansible is everywhere in my workflow. I work with AWS, Azure, Docker, KVM/QEMU, and more Linux distributions than I should probably admit. Fedora Workstation is my daily driver. It does what I need without getting in the way.

What You’ll Find Here

This space is for documenting what I’m building and learning:

Modern Infrastructure & SRE Kubernetes, containers, cloud platforms, automation, Infrastructure as Code. The day-to-day work of keeping systems alive.

Cybersecurity System hardening. Threat modeling. Security automation. The quiet work that happens before incidents, not after.

Vintage Computing Classic Macs, C64, Apple II, IBM PCs. Restoration projects. Programming for old systems. Making obsolete hardware do useful things.

Hardware Projects Microcontrollers. 3D printing. Embedded systems. The physical side of computing.

The Philosophy

Old and new systems teach each other. The clever hacks that engineers used when memory was measured in kilobytes? Some of those patterns are still the right answer today. And understanding modern distributed systems helps me appreciate what mainframe designers figured out decades ago.

I focus on what actually works. Not theoretical perfection. Not best practices that sound good in blog posts but fall apart in production. Real solutions that solve real problems.

I also believe in working with AI, not against it. Human experience brings the practical requirements and real-world constraints. AI helps with pattern recognition, edge cases, code quality. Neither perspective is complete on its own. Together, they build something better.

Reach Out

If you’re into SRE, security, automation, or keeping old machines alive—I’d like to hear from you.
