Create some open source projects in the field you are interested in! This is a great way to demonstrate that you know what you're doing, especially if others are using your project and collaborating with you. When I interview people I always look at their GitHub and dig into their work. Just make sure that your code has tests and has ok documentation. Bonus: if one of them gets popular you'll have companies coming to you.
