Could someone provide the Apex code for a trigger that automatically pulls the opportunity creator/owner to the sales team on the oppty? 

Here is an example: 

User: John Smith
Profile: CDS

Whenever this guy creates (owns) an oppty, i would like him to immediately be added to the Sales Team with the team role "Sales - CDS"
* all of the team roles say "sales - " and then the department which always matches the profile name.

Can anyone help? :-)
