This story has some interesting ideas, but suffers greatly from being a Mary Sue[1] fanfic; the protagonist is a vastly overpowered author self-insert.
The real Mary Sue in this story is Hermione. Harry actually has massive problems that he doesn't recognize until after the story ends. Also, the primary antagonist have been massively buffed to compensate for the improvements to Harry.

But it hasn't gotten much interest here since March 2015 -
