What Am I: Finding Myself in IT

I'm considering quitting my job in healthcare to pursue a career in IT. But I'm frankly unsure what I should call myself or what jobs I should apply for. Maybe you guys have some thoughts?

I'm in my 40's, worked a few years as a consultant in the 90's. Like installing Windows, setting up networking and hooking up DSL. Since then I studied something different and worked many years in healthcare. But I kept my interest in IT. Today I have several servers, both at home and in the cloud. I run Kubernetes, Ceph and have become quiet comfortable with that. I'm not a programmer although I usually can read code and adjust it to my needs. I'm more at home in the shell (bash, zsh) and have written a few scripts to automate stuff. And now I also have some experience in container orchestration (read kubectl and manifests).

I'm not sure what I expect from you guys. Maybe just some free associations on my thing.
