This one is a long chain of events.

The previous professor resigned of this class too close to the first class.

The coordinator asked the head of the IT department, then he asked his right hand, who asked a friend, who asked my then ex-girlfriend(now wife), who knew the topics needed for the class(CRM, BI and DS) were things I worked @ Oracle.

Then I communicated all the way to the coordinator, We talked and well I have been teaching there from 2016 to date =)
