Operating Systems
3 platforms
The platforms and tools I have run in this group, with how long I have run them.
Linux (RHEL & Debian)
12 Years of Experience. Linux is what got me interested in computers in the first place. Being able to change how software behaved and how the UI looked was a big deal to me early on, and it still is. These days I mostly run macOS on an M4 MacBook Pro, but most real work still happens over SSH on Linux systems and container hosts. I spend a lot of time building containers, so yes: Linux turtles all the way down. This xkcd is relevant.
Windows
4 Years of Experience. Four years of Windows endpoint support, including a Windows 7 to 10 migration across Schweitzer Engineering Laboratories, and three years running Windows patch and configuration management through Syxsense Cortex. My own development happens on Linux and macOS, but Windows fleets are an environment I have shipped real work against.
macOS
5 Years of Experience. Daily-driver laptop platform (M4 MacBook Pro). Solid hardware, good terminal environment, and easy SSH-first workflows into Linux systems.
