This might be the imposter talking but I feel like a fullstack developer without a backend, I have invested many years into JavaScript and node and perhaps less time in "traditional" backends. I enjoy writing c++ and rust but often with a web development focus.

I notice that most job roles in fullstack are either Java or C#, my question is this, how can I be interested in either or, I can do alot in node. What would I enjoy more Java or C# or are there roles in Rust?

I just don't know where to go with my career from here.
