Thanks for asking, OP. I’m in a similar boat, except I don’t even have a computer to get started with yet, only an old phone if I wanted to use that (not trying to do things on my daily). Thinking of buying a raspberry pi and diving in but dunno where to start.
Have plex and someone kind enough to share their library with me, but it doesn’t have everything I want. Could be worse tho, I suppose.
See what you can get by putting some subtle feelers out. Talk to a recruiter or two. Best time to search for a job is while you have one, but you don’t have to commit to it full time unless shit really hits the fan. You’re more likely to get written up than fired initially anyway if he’s not the owner, erratic or not he has to answer for that.
Continue working towards whatever certifications you want in the meantime, especially if the job pays/reimburses you for it.
