I Don’t Believe in Full-Stack Engineering
I once met a software engineer who said I was not full-stack because I didn't know how to add to the Linux Kernal. I once met a hiring manager who said I'm not front-end because I don't know how to vertically shard MySQL and "every front-end developer knows how to do that." Technology stacks differ per company and the definition of the title will also differ. That doesn't mean it doesn't exist.
