I would start looking at building systems that could be used internally. If you are being overruled, you might as well put some time into something useful. I don't know exactly what your company does, but you might want to look at building a: - CRM system - Specialized Bug Tracker - Continuous Integration Software - Build a Test Harness I know these system exists, but if you have time it is good experience. Also, ideally, you should work on things that you can take with you when you leave. However, this is usually not possible. I have had friends who built open source projects at home. They then convinced their boss to use it and contribute to the project. If you keep your mind open, I am sure you can think of some creative ideas.
