At the moment I use C# with Unity. I have been a developer for 2 years now. I want to make games as a hobby and do something else programming related. I have knowledge in C# and there are loads of MVC/.net in my area so it seems like a good idea to go for.

I want to built up a portfolio so I can start applying for jobs but not really sure what I should do. Any ideas of what I should make and what I should be studying?
