Change learning technologies?

Question

Ruby on Rails

I recently started learning how to program a little. Ruby, rails.
Now I can make simple websites, a la blogs, online stores, etc.
In the process, I realized that I don’t want to touch the frontend at all. Not interested.
And vacancies with rails are a solid full stack.
Is it worth changing the technologies being studied? (to the same python / django?) Or am I looking at it somehow crookedly and with rails you can find vacancies for a clean backend?

Answer 1

What is the difference between Ruby/RoR and Python/Django?
If you like the ruby ​​/ ror stack itself, then you should take a closer look at the vacancies, in many cases only basic knowledge of the front-end is required, so that you can somehow communicate with those who are directly involved in this.

Answer 2

Writing a system for an online store is at least 50% of the backend, it is difficult (if you take a normal system), and, therefore, one full stack is not suitable for this. Here it is desirable to have one clean backend worker.
So, a clean backend is needed already for such work.
For really complex projects, pure backend developers are required, regardless of the chosen programming language. And often more than one.
