Fernández started his career on stage at age 19, and developed his directorial skills on stage. His directorial debut in filmmaking was with the short film
Blue Sky produced at the
New York Film Academy, which was selected to the official competition in several international film festivals. The 2016 film
Tamara, inspired by the life of
Tamara Adrián, is about a successful lawyer who takes the decision to start a gender transition, and Fernández plays the lead role as Teo/Tamara. In 2022, Fernández directed and shot a film using his
smartphone, based on a story by Venezuelan screenwriter
Mónica Montañés, and workshopped with the actor Veronica Oddó in
Santiago, Chile. His wife
Mimi Lazo was producer and lead actor of the film, called
Desconocidas (
Unknowns). He described it as a very personal project: "The opportunity to tell a story by Monica Montañés about the loss of identity that comes with having to leave your home, your family, your country, your house, is the story of 7 million Venezuelans scattered all over the world". The scenes were captured via Zoom, in front of an invited live audience. Lazo was in
Madrid at the time, Oddó in Chile, and Nina Rancel in Los Angeles, but the film shows them in one apartment.
Unknowns was screened at the
SmartFone Flick Fest in
Sydney, Australia. ==Radio and stand-up==
