Looking for help understanding how parts of a full stack mobile app are connected

Hi guys, I have very little programming experience so I am in way over my head here but I’ve been asked by my boss to make an android app so that is what I aim to do. After doing a lot of research and just starting to get comfortable with some vocabulary I’ve put together what I’ve learned and how I think the pieces of the full stack app will be connected. Can you please tell me where I am wrong/make no sense at any points in what I describe below?

In an MVC framework, 1.) the controller manipulates the model, 2.) the model updates the view, 3.) the user sees the view, 4.) the user interacts with the controller, 5.) repeat

I tried to find a way to use only javascript and, honestly, this might be embarrassingly wrong but here it goes: 1.) The API would be built using Knex to simplify the code 2.)The Knex API then manipulates the database which Ive chosen to make with SQLite3 because it would be structured database in this case 3.) Then Redux would be used to format the data sent to the view 4.)Next React Native would be used to built the view on the app 5.) And the controller would use Express since it would launch the node.js RTE and begin executing all of the other steps(Im guessing im not even close with this one, not even sure if Express has anything to do with mobile apps)

Sorry if this is nonsense, but I’d really appreciate some feedback. This is all new to me
