Organization is the hardest part for me personally in getting better as a developer. How to build a structure that is easy to change and extend. Any tips where to find good books or online sources?
You can learn how to create clean, readable methods and classes with a book (1).
You can learn how to refactor old methods and classes with a book (2).
You can learn how to organize a small team to allow fast iterations with many books.
But building a project lasting more than a few months with constant changes in the requirements, new developers every month, new SDKs and frameworks every 3 days, without the code rotting to death and everything going out of control is a different story, at least for me.
I guess you just learn by watching old guys do what they do after decades of experience...unless someone has a magic book for me?

I was lucky that this was one of the first things I had learned as a developer out of school. It was a little different because the projects were small enough to be solo, but it was humbling because all of the mistakes were my own.

This is a very good book on subject, very clear:
