I was this person for the first ~17 years of my career. With the caveat that I was developing features on the bottom of the stack in C but would frequently implement features all the way up to a web interface running on an embedded device.

I'm in games now and I have a specific focus and I really, really enjoy it. Maybe it's my old brain, maybe it's because I have young kids now, I don't know, but I really like that I don't have to context switch so often now.
