I helped launch Feral Audio in 2012, and from cradle to its unceremonious end in December 2017 I served as its technical & design lead. I'm sad it had to end, but I got to design a little of everything at Feral, and I'm leaving significantly better/more versatile than when I started.
Above is a quick cross-section of the kinds of things I designed while at Feral. I was responsible for the website design, around half of the podcasts' artwork, about half of the merch designs, and basically any spot graphics we needed (including business cards & promo/convention art).
