Olá! I don’t see anything that would hold you back.
Since you’re a designer, I would recommend learning about Bubble’s designer and its responsive engine. I would highly recommend looking at some of the Buildcamp stuff (I’ve got a post with the links and some key take-aways).
Certainly learn how to manipulate Bubble. There are tons of courses that Bubble has put together and tons of YouTube videos out there with very helpful content (lots of stuff in Portuguese, too).
