I am not a Rock Star developer

Rock is chaos , destruction, go against the order. I love rock and roll but I am not a Rock Star coder

So when I see “ We are a rock band business, ready to take the world, so we need a Rock star developer to rock the world with us”

Well that really turn me off.

If you want to capture  my attention write something like:
“We are two guys and a Girl building our business,  we are looking for a Violinist coder, who execute clean notes, pleasant sounds and harmonious music”
