Trying to understand how Reddit’s phone-app system works behind the scenes.

I’ve been trying to figure out how the Reddit phone app works, and I’m wondering if anyone here has ever looked into how a big app like that is built. I’ve done lots of projects that use normal APIs before, so some parts feel kind of familiar, but this seems a bit different. When I check what the app sends out when you try to make a post, it looks like it sends a bunch of different messages, not just the one that posts the thing.

So I’m mostly asking if there’s anything I should watch out for, or if anyone has learned anything from studying how other big social apps work. I know people here don’t usually share all their tricks, but any general ideas would be really helpful.
