When I convert a lead record into a contact and a deal then a the contact record will have User AAAA as record owner, and the contact record will have User XXXX as the record creator.

I don't have any workflow rules in Contact module.  I use the blueprint like the image below for lead conversion

what I really want is, when contact record is created, then I want to make 'Contact Owner' field to be the same as 'Created By' field.

is it possible to to this using workflow rules? I am also ok if it need deluge function to be executed, could you please share the code?
