Are you letting the potential employers know that you are homeless or letting them see any indication of it? It's probably not going to help if you are. People will judge you for being homeless. Don't let your prospective employers find out, even through inference.
Have you figured out what you're doing for your address? Do you have a nice set of clothes, haircut, and shave before interviews? If you don't put a residential address on your resume, it isn't going to help you.
I am sure you're already getting enough advice on the technical aspect of finding a job in this thread. You can know anything, but if you can't get through the door because humans are superficial you're still screwed.
I would do this: hit up freelancing websites and make enough money doing small gigs online to get an apartment or rent a room with somebody. Those sites have a bad rap, but I promise you I've done well enough on them to say it's worth your time. Accept a low rate at first to get feedback and ratings on whatever site you choose. Better freelancing companies also poach people from those sites. If you have a good profile, someone will ask you to come work with their clients instead. It happened to me.
Worry about creating a marketable image: your online profiles personal website, github, stack overflow, linkedin etc, your appearance (fitness will make you more marketable), and your sales pitch. Write a pitch and rehearse what you're going to say in interviews. They're going to ask you what you've been doing! My advice: don't tell them about your recent misfortunes. It might be true, but would you want to buy a car that had mechanical problems and was found abandoned on the side of the road, three years later? You'd want to buy a shiny new car. You need to become a (good) used car salesman and you will find yourself in a job.
Good luck in your search.
