Analytics Algorithm Add-In for PowerBI

Hi - I'd like to develop an add-in for PowerBI that runs some proprietary analytics algorithms.  They involve multiple database queries, etc, as well as lots of custom logic.  Eventually I'd like to distribute via the AppSource.

1) Is this possible to do in principle?  I am finding it difficult to find content around developing algorithms against PowerBI data.

2) What resources would be most helpful to do this?

I already have a standalone application (see factorprism.com).

Any help you could provide would be greatly appreciated.

Thanks,

Dave
