What is the .NET developer roadmap?

Hi,

I want to work remotely to the US companies in the C# field. I already know:
HTML, CSS, JS, PHP, SQL, C# and ASP.NET Core MVC and extras like: Restful API etc.

And I create tools in my own world.

But when it comes to Jobs and Companies, I get so complicated like there is so much to learn:
- Design Patterns (don't even know where to use in real life)
- Repository Pattern
- Solid Principles
- Enterprise Architectures etc.

And too many other things, and don't even know what a proper roadmap is. Please help me.
