Where can I find materials on the architecture of a developing project?

Question

Programming

The main task is to start the development of a developing project correctly.
A developing project is a project that increases/changes (sometimes very unexpectedly and drastically) its functionality.
The main problem is that when adding / changing functionality, you often have to rewrite most of the project. Somewhere it is necessary to divide the module into two independent ones, somewhere, on the contrary, to combine or something else.
As a result, a lot of time is wasted.
I am looking for materials to work on similar projects.
Thank you.

Answer 3

Only an experienced specialist can design the architecture of a large project well.
"Materials on architecture" depends on your chosen language/languages, technologies (and on the OOP paradigm used, functional, procedural, etc.)
