If I can do it, others can do it, too. I even built an entire full-stack framework (w/ a custom components system + Node.js back-end), deployment system, database, and CSS framework (and now those all run my businesses). When I started, I didn't have the slightest clue beyond some basic HTML and CSS. I think people limit themselves too much trying to fit into the narrow containers of a job title/description. I get why, but it's worth asking yourself what else you're capable of beyond your job if you're eager to learn.
