User Profile Pre-Canned Application

Was wondering if there is a set of open-source code which uses dash to implement a user profile section of a website (similarly to on this site, were i to click on my user icon in the top right and select “Preference”. everything under there)

it seems like a somewhat complex thing to write yourself, but the look and feel of it across various message boards/etc is more or less the same. i searched around but didnt find anything.
