Hahaha, I actually got interested in marketing from reading patio11's stuff back in the day! However marketing is definitely still more of a hobby for me, my main focus and day job is frontend DevOps. I do love treating this whole social media game as an engineering problem though.
My channel is still small, it's mostly software engineering career advice and personal finance (videos like this https://www.youtube.com/watch?v=o4YeX6tbR60).
