Luis Vielma, 22, was one of the 49 victims of the terror attack in an Orlando gay club last Sunday.
Author J.K. Rowling paid tribute to Vielma on Twitter, after learning the young man worked at The Wizarding World of Harry Potter at Universal Studios.
In his obituary, his family said working at the attraction was a "dream come true" for Vielma, who was a big fan of Harry Potter.
"He loved being able to go and be part of that every day he worked," his family wrote. "There was no greater experience for him at this time."
