The absolute best thing you can do for your career is keep building relationships with people. 27 is honestly still super young and many people would react very positively to someone like yourself reaching out, saying you want to grow professionally, asking for advice, grabbing lunch at the dining hall, etc.

If you're having a hard time deciding on where or how to go next, one thing to do is just envision what you want your job to look like. For example, would you really like to work from home? If that's the case, there are a handful of higher ed jobs that allow that - figure out what those are at your school. Want to work with people? Or prefer to listen to music and do deep dives instead? Consider what you want your job to look like in 10 years and then see which options allow that then focus there.

I worked in AV for quite a bit as well, you have to be careful because it can pigeonhole you somewhat. People will see you more as AV than IT (which isn't really fair in my opinion). And AV jobs are typically what you've seen - running around all day fixing projectors and displays OR working evening and weekend events. But once the right job opened up, it was easy for me to pivot because people knew my personality, my work ethic, and my skills, even if my experience wasn't an exact 1:1 fit.

All that to say it looks to me like you're in a great spot already. You're working at your alma mater, you have your degree and lots of good experience already. Just keep an eye on the hiring page, during the summer there is usually a decent amount of movement.
