I recently changed careers myself. My advice is to look at positions that look interesting/are in high demand, check out the technologies that they are using, learn them, build them and put them on your Github. And make sure to put the keywords of the technologies you know on your Linkedin - if you actually know them (because otherwise you will embarrass yourself in a technical interview).

Since your time is limited, make sure every time you sit down to code you are learning something new rather than retreading the stuff you already know.

This won't be easy - you will have to be stubborn and persistent and really commit to it. I for one got here because I became obsessed with tech and spent countless nights coding instead of socializing. But the rewards are there if you have the passion to stick it out.
