So I'm taking the plunge. I officially bought a high performance mac so I can get into the app development game. Now comes the planning stage.

​

For the front end I already know what I am doing, React Native with Expo and Typescript. This should help me make a great front end without many stupid errors as I made when trying bare React Native. But the backend is what I'm wrestling with. I was originally going to just do Firebase cause that seems to have a large base of advocates for it. But I worry about scaling up how expensive it might get. But from what I understand migration to a custom built backend would be very painful. Should I put in extra time now to learn backend dev or should this be a future problem and just make the MVP with a BaaS so I have something to start with.
