Working as a dev in east bay? (SF bay area)

I live in the east bay, moved back to the bay area about 8 months ago, thus far have been working in SF doing the commute each day which is getting to me. From job searches it seems there aren't many options out here, at least not with smaller companies. I'm looking to get into doing node js so looking for a company that uses this. Just curious if anyone has any advice, info on whether there are many companies in the east bay. thanks
