Your best bet is to look into a programming boot camp training program. As you have seen Ph.D. academic programming deals more with research while commercial programming deals more with delivering a product as fast as possible. It's two different mindsets.
1st decide on what area you want to specialize in and then look at a reputable boot camp that fits your goals. You can do it on your own but it's going to take you a lot longer and it's hard to focus on what you need to learn. Also, if you could do it, you would have done it already. The advantage is that you're already used to the scholastic environment and you'll be able to do very well and be even well ahead of everyone if you challenge yourself rather than strictly following the curriculum.
