Sef Cadayona

Sef was cast as the teen Wally Bayola in Magpakailanman in early 2013. Along with this, he became a regular castmember in the gag show Bubble Gang because of his comedic capabilities. Aside from his weekly Friday-night stint in Bubble Gang, Sef was also hired as the gay character Stefani via Vampire Ang Daddy Ko.

So far, Sef has one film for 2013, and that is the Marian Rivera - Richard Gutierrez-starred film, My Lady Boss, under GMA Films and Regal Entertainment.

In 2012, Sef was part of the Bea Binene starred TV series, Alice Bungisngis and her Wonder Walis, as Tomas, one of the assistants of Esmeralda (Jean Garcia).

During the last quarter of the year, Sef was part in the Filipino adaptation of the hit Korean series, Coffee Prince, as Baldo, the ever loyal and overly submissive suitor of Andy's sister, Mylene.

Also in 2012 marked a milestone for Cadayona for his career in the silver-screen. He had four films in a year, including two from GMA Films (My Kontrabida Girl and Just One Summer). Sef also made two independent films, one is under the production of Cinema One entitled Slumber Party; his character was Jonel, a guy who wants to be in a frat and the part of his initiation was to sneak in a house. The other one was an entry in the New Wave Section of 2012 Metro Manila Film Festival with a title Gayak. He played a gay character, but unlike his previous gay roles which are of comic relief, his character in Gayak pleaded for sorrow and sympathy. Because of his performance in the said film, Golden Screen Awards for Movies awarded him the Breakthrough Performance by an Actor award.

In 2011, Sef was cast in the second episode of Spooky Nights series entitled "The Ring Tone". He portrayed the role of a gay character, Vanessa. Come mid-2011, he became part of the danceserye of GMA Network following the success of Diva - Time of My Life. In December 2011, Sef had his first film through the 2011 Metro Manila Film Festival and one of the most successful movie franchises of Regal Films. The film is Shake, Rattle & Roll 13.

Sef is being called as the male Sheena Halili for portraying sidekick roles in the series that he belonged to. The series where he became a sidekick are Ilumina (2010) as the best friend of Aljur Abrenica, Time of My Life (2011) as the gay best friend of Kris Bernal, Alice Bungisngis and her Wonder Walis (2012) as the sidekick of Jean Garcia; in Together Forever as best friend of Julie Ann San Jose and in Mundo Mo'y Akin (2013) as the best friend of Alden Richards' role.

He was considered as one of the threats for the boys because he was very active and he excelled in almost every tasks that were being given to them. During the dancing week given Douglas Nierras as the mentor, he gave 100% of his performance and had a chance to perform on stage paired with Nina Kodaka who finished 6th in the competition. However, during that week, he was included in the bottom group where Zeryl Lim went home.

In early 2010, he already began to be an actor by having a guest role in the comedy series, Diva, as the rival of the character of the character of Mark Herras in a dance contest. He became also a guest for several episodes in the now defunct show, I Laugh Sabado wherein he portrayed different roles to show his comedic skills. In mid-2010, Sef had his first regular role through Ilumina which was shown in prime time. The said show was led by Aljur Abrenica, Jackie Rice and Rhian Ramos.

Sef made it to the final fourteen last November, 2009 with Steven Silva and Sarah Lahbati who got the Ultimate Survivor title for male and female, respectively.
