This is so well done. Really impressive. It seems like a great tool for both designers and developers. The more I develop responsive sites, the more I realize how difficult and tedious it is. Hopefully, this takes a lot of the pain away.
I'm also super jealous you have a brother that you can develop a product with. My brother is a systems guy and doesn't want to create software at all.
