I’m hunting Portuguese names for a book and I found:
m Portuguese, Catalan
Short form of Joaquim
If this was a comedy I’d name him Joaquim just so everybody could call him Quim.
For the record, I think his name’s going to be Sergio Cardoso.
UPDATE: Sergio has been nixed by the Keepers of the Testosterone. Fabrizio Cardoso is a strong contender.
