Consider interviewing for a developer management position. Instead of focusing on specific languages & technologies, maybe take a step back and figure out how to apply other things you've learned: how to direct a project, how to take higher-level ideas and turn them into realities. Those types of jobs tend to be more marketable than "I use X, Y, Z technologies".
If not management, I'd still say try to get a little more "meta" than just "I know Rails, Node..." Market yourself at a business-level, if that makes sense. In my opinion, the tools you use to solve a problem aren't as interesting as how you approach a problem and solve it.
Just some thoughts, good luck!
