I’m the Senior Digital Designer at an agency, so I handle everything from wireframing/mockups to ad creative and landing pages to storyboarding video to brand strategy. Everything I do is digital and marketing-focused, so lots of UX, UI, brand, and general design. I do more UX-related work than anything, but no day is the same - which I love. TLDR; a pretty generalist digital designer, lol.
If you don’t have a design background, start where you are! Plenty of free and low cost courses online you can do. After just recently hiring a mid-level designer, I can tell you an excellent portfolio is usually more important than what college you went to. (Side note: I didn’t go to college.) Keep learning, keep practicing, and keep growing - over and over. The design industry is always changing.
I haven’t tried these course, but worth sharing:
