You're looking at this question at the wrong lens. The question shouldn't be "where can I find programmers" it's "where can I find reliable programmers". I specify because on reddit, fiver, etc you can hire some dude to do work, but you may get a quality product you want. This is part of the point of networks: you know a guy who is a hard worker and competent.
If you don't have a network, I say you want to find people developers at game jams. At that low stress environment, if the guy isn't a good programmer you can cut him loose: otherwise he's a keeper and will be good for future contact.
