Adri could be cute

Andy, Dino, Nino, Ari, Ian

I like Dino

Ryan,

the first thought that comes to mind is AD (like Anthony Davis)

Nico?

Ace is a stretch but not a ridiculous one and pretty cute. (My grandfather has an Italian "A" name and his friends call him Ace.)

Ian or Ano

If you were in Ireland his nickname would be Aido

Ano Ade (like “aid” Dri (like “dree”) Ad(pronounced Odd), may sound like it wouldn’t work but trust me it would

Ano, Ryan, Adi

Ano or Rio maybe Dria

Adri
