From a very young age, he demonstrated a great talent for entertainment, excelling at events at his school, The Grange School,[5] and later at Colegio San Ignacio El Bosque.[6] This innate talent led him to appear on television at a very young age, participating in the "Children's Clan" segment of Sábados Gigantes, variety show hosted by Don Francisco.[7]
In 1992, he graduated from high school and enrolled at UNIACC to study audiovisual communication, a degree he never completed.[8] Five years later, Verónica Calabi invited him to participate in the radio program Hola Concierto on Radio Concierto.[8] At the same time, he enrolled at the same university to study journalism, a degree he also never completed.[8]
In 1997, Calabi, who had signed a contract with the private channel Megavisión, invited Viñuela to participate in a casting call for a competition.[8][9] Thus was born Mekano, one of the most successful youth programs on Chilean television.[2] Viñuela established himself on that show as one of the most successful youth hosts.[2]
Beginning in 2003, Mekano's ratings began to decline, partly due to the launch of the TVN program Rojo: Fama contrafama. Viñuela then began to rethink his television career, taking over as host of the nightly program Sábado por la noche (SxN) in 2004, previously hosted by Juan Carlos Valdivia.[10]
In 2005, Viñuela took new role, hosting the morning show Mucho gusto, which he hosted until 2020.[11][12]
Since 2022, he hosts the talk show Tal cual on TV+ alongside Raquel Argandoña and Paty Maldonado.[4]
