Everyone hired a full stack developer cause they want them to handle everything. I mean literally everything from the front-end, back-end & dev ops, basically everything until the system LIVE & operable. We get that! But those title should have matching compensation aka salary. We can do the work. But that doesn't mean we will do it. Unless we get paid more. Plus it's ludicrous to ask a full stack developer that currently handling a project that used, let's say, JAVA based program (desktop application) from the front-end, back-end & dev ops stuff to handling another project that used totally different language like maybe JavaScript Web based application simultaneously. Crazy huh?
