I already know how to write code, what's next?

Question

Software design

I can write code, I know all the nuances of my language, but what do I do next?

Previously, I did not understand all this talk about architecture, but when a more or less large project appeared, I suddenly began to understand that it was really important.

It's not difficult for me to understand some framework or technology - they all have excellent documentation that teaches how to use this thing, but does not teach how to make architecturally correct projects based on it.

In which specific direction should I look in order to learn how to write not just code, but competent code in a properly designed project?

I've heard a lot of cool terms like Dependency Injection, Domain Driven Designand Гексагональная архитектура, but I don't think those are the things to start with.

In general, I am interested in two topics:
1) Architecture
2) Clean code

Answer 1

Robert Martin - Clean Architecture (SOLID)
Eric Evans - Domain Based Design (DDD)
Definitely start with Clean Architecture, then read somewhere about hexagonal architecture, then read Evans.
The topic of the architecture of building a separate application (which can be part of a larger application) really fits into 2-3 books and articles with explanations.
Then, you need to learn UML at a basic level in order to visually design the application's architecture.
Then take draw.io and design. You want a pet project, you want your working project, then propose changes to the team.

Answer 2

Further books on clean code, design patterns, paradigms, architecture, good practices and more.

Answer 3

Look in the direction of some liked projects, like awesome- or see the official style guides
