Capturing Activity in User profile page

We have a requirement of capturing a detail for logged in users when they will perform an operation from a page.

Page is created using sling model. Onclick of a button, a dialog will open and on click of submit button of the dialog, some custom data will be saved in mongo db.

The user also can update the same data later point.

Once user updates/creates an entry in mongo db, the same activity needs to be shown in user profile page under MyActivity section.

MyActivity in user profile is implementing activitySteream component of social community.

Please suggest a way in which this scenario can be implemented in AEM.
