What would be interesting for you? What would you like to do?
Does your employment contract allow you to do this in your own time?
For me, I'm more interested in a particular domain, rather than the technologies around it. So, for example, I like marine biology, so the projects (and work) all revolve around that. You might like distributed databases, so why not work around that. Find what interests you, and move towards that direction. Some people have contracts that say that their employers owns all their work even when they are not at work, and some say they cannot do open source work, so this could be a constraint.
