Your question is open-ended but if you have solid chops in a good amount of those you will find quite a few jobs are available. I listed them in roughly the density they have in my automatic job emails. I recommend something like http://indeed.com's automated mailers. They are highly tweakable.

Update: meant to say: you'll need to whittle down what you want to learn to specifics if you want pointers/links/tutorials.
