About me

Hi, and welcome to my website! I’m John, a career educator with over 15 years of experience who’s now transitioning into the tech field--a lifelong interest that’s finally becoming my career focus. Originally from the United States, I’ve been living in Japan for the past 15 years where I teach English at a junior high school in central Nagano.

What I’m working on

What sparked my recent dive into technology was a TrueNAS server I set up in 2019. It began as a simple quest for more storage with a Raspberry Pi and an external hard drive, but quickly turned into a full homelab experience when I purchased a used SuperMicro server on Yahoo Auctions. After several changes (homelab... right?) and a recent interest in Kubernetes it's now a system of interconnected services and hardware including TrueNAS for storage, that original Raspberry Pi as a docker host, and a stack of three Lenovo ThinkCenters as a bare metal Kubernetes Cluster. You can actually find out more on my Homelabo Github page here.

I’ve also recently been very interested in Go programming, working on small projects here and there when I have time. Recently I put one of those projects, Jailhouse Roll Call, on GitHub. It’s just a simple tool for me to check on the status of the several jails that were running on that TrueNAS server.
