Most job descriptions want X years of experience in {language or framework}. Unfortunately, they rarely care how many technologies you know. They're looking for years of experience generally, and experience in their tech stack specifically. I'd recommend picking the tech you feel most comfortable with and building out a couple of bigger projects. Maybe put them on GitHub as part of your portfolio.
To be honest, if I were a hiring manager my concern wouldn't be that you don't know Ruby or Elm well enough to build something valuable; it would be that you haven't been deep enough into any one project to understand the pitfalls and roadblocks associated with an enterprise-level, long-running product. I see programming skills as mostly portable from language to language, but you definitely need some kind of specific experience.
If I were you, my goal would be "Jack of all trades, master of one."
Sometimes roadblocks and bottlenecks I've found to be team and people problems at times... nothing necessarily to do with programming. Ever had a group project where things just went sideways at school?.... lol

Thank you Isaac!
