I've had the opposite problem. I'm a front end dev and have worked with a lot of full stock people: none that I really respect. I recently came across a real personable one but at the end suffered from the same issues: believes his acquired knowledge as a backend dev transfers over to full stack. I have my own flaws but am very self aware: I don't implement anything shiny unless I thoroughly review the dom validity, responsiveness, accessibility, then finally functionality. Most people only review functionality and it's sad.
