Start with building an app that you can be proud of. Others have mentioned working for free, but if you're going to do that, you may as well build an app for yourself. Treat it as a client project and be willing to put some money into it to keep yourself committed and ensure its success. Once it launches, you have an instant portfolio and hopefully some Github contributions that come out of it that you can point to. This is the route that I am going with. I'm about 60% done with my app.
