How do I (23M) find nerdy/geeky or career oriented friend groups around my age in Fresno?

Hi, I've just turned 23 last week and have suddenly feel lonely since I just got out of a relationship very recently. A lot of my friends are from college so they live far away and the ones I have in Fresno are few (2-3) and they are unfortunately a tad more introverted than I am. I love pc games although I don't play actively anymore, am slightly nerdy, but also a little sporty as I've done muay thai for 5-6 years whilst being the president of my school's club.

I also have a cs degree and am working full time - I used to spend a lot of time with my ex and when I wasn't - I'd be at the gym or focusing on career development. I don't want to withdraw into my own shell and just work all day even if it's good for me; I'd like to try to make deep connections again. I feel like my type of people are hard to find without having mutual connections, anybody know where to look?

(Also I'm asian if that helps ¯\_(ツ)_/¯ )
