Is it possible to become a Ruby on Rails backend developer? Or is there only full-stack?

Question

Ruby on Rails

I want to become a back-end developer and settled on ror, but its main pattern - MVC - implies both the server side and layout... Is it possible to write only back-end on it? Or will you have to make up the bulk of the projects yourself?
(tk, as I understand it, there is no hard division in ror)
Thanks for the answers.

Do you want to typeset, do not want to typeset, master master.

Usually, you don’t have to typeset, but you still need to know HTML + CSS + JS.
