I am a full stack guy who was doing 50/50 front-end vs back-end till last year. But since then, I've started moving more towards the back end as I simply am not able to keep up with the newer frameworks and libraries coming out everyday.

What is worse, a lot of employers have already decided that if your app isn't written in React + Redux + whatever-is-hot-today, it isn't worth doing. I like to keep my stack fairly simple, and my approach apparently doesn't work.

I still do a fair bit of front-end development, but only when its on my own terms.
