I've worked with few incompetent people till now, but one guy who stands out is my peer who is a "Lead Developer".

First of all he knows nothing!! Even Jon Snow knows something, but this guy knows absolutely nothing. And on top of that he has a hard ass attitude. Never sticks to coding standards, pushes unwanted configuration files to Git, uses too many nested loops even when not even a single one is required.

And when I suggest him something, he starts giving these lame ass reasons and tries to avoid my comments. Then I say, "good luck with that buddy" and move on!!
