In San Jose for 2 weeks, how can I best use this time to aid my career?

Hey all! Long story short, I (was) a Jr. Dev for about 9 months. I got consistently stellar feedback and enjoyed the job, but ended up putting in my notice for personal reasons. This was about two months ago. I still enjoy tech and tinker with personal projects, but I accepted a "fun" job outside the tech sphere as the bar manager for a travelling pop-up bar/stage show. It has indeed been a lot of fun and I've been to over 10 cities in the past 2 months all across the US. This job is also what's bringing me to San Jose.

As fun as it's been, the nature of the job makes it a temporary arrangement so I'll need to re-enter tech eventually and while I have some time in the tech capital of the world I'd like to see if I can use it to my advantage. I have very little social media presence, no linkedin, facebook, etc so digital networking isn't really viable. Does anyone have any suggestions for how to best make use of this time?

Thanks in advance!
