If you are looking to become more competitive as a candidate, I strongly recommend that you look at one of the more popular languages / frameworks instead of focusing on Ruby on Rails.
Despite the major investment made by Stripe and Shopify, my experience is similar to that of this commenter: https://news.ycombinator.com/item?id=40161561 - like them, I've found the open source libraries available in the Ruby + Rails ecosystem to be aging and less well supported than that of more popular languages / frameworks like GoLang / Java / Python.
Rails is delightful to work in and very thoughtfully constructed, and the Rails community is helpful and welcoming. However, if your priority is to maximize your chances at getting hired, I would look towards GoLang / Java / Python etc, which are far less enjoyable to work in but far easier to find jobs for.
