I'm a software developer new to the bay. I'm starting to feel like my overly generalist skill set is holding me back at this point and I would like to spend a year or so extremely focused on learning one technology. I'm pretty sure that technology would come down to Ruby on Rails or Angular.
I have about 6 months experience in each. I enjoy angular.js more, but I'm okay with Rails. My perception is that the job market is hotter for Rails. I also perceive that angular.js has more potential for growth in a year, but also potential to shrivel up.
I don't really care much about making more than 90k or so, so higher income potential doesn't matter much to me. I'd really like to land in a start up in the SF, but I'm open to other locations + types of work.
