From an early age he began to show his talent, and at the age of 11 he began composing his own music and lyrics. It was not until 1984 that his interest in music turned professional, and he assumed the stage name Aleks Syntek, ("Syntek" being a shorthand name for "sin teclados", lit. "without keyboards;" the name was given by a friend from whom he had asked to borrow a keyboard.)
In 1989, Syntek composed the songs "Muévete a mi alrededor" ("Move around me") and "Siénteme" ("Feel Me") sung by Mexican artist Sasha Sokol.On Mexican pop trio Pandora's album, "999 Razones", he wrote "Invisible" and "¿Por qué seguir?" with Alex Zepeda.In 1990, he wrote "Sacúdete" ("Shake Yourself") and "Escapar de ti" ("Escape From You") included on pop group Timbiriche's album "10". The same year he formed a group called Aleks Syntek y la Gente Normal. His first album, "Hey tú!" ("Hey You!"), included the single "Unos quieren subir" ("Some people want to climb"), as well as "Te quiero así" ("I Love You Like That") sung with Sasha Sokol. In 1998, he covered the song "Preso" ("Jailed") included in the album "Volcán: Tributo a José José", a tribute to the singer Jose Jose.As of 2008, he is working on a crossover album for the English-speaking market. The album will consist of English versions of his past Spanish hits, such as "Duele El Amor" (Love Hurts) and "Intocable" (Untouchable).In 2008, Syntek collaborated on song "Aquí Estoy Yo" with singers Luis Fonsi, David Bisbal and Noel Schajris, a song included on Latin Grammy Award-nominated album Palabras del Silencio
by Luis Fonsi.On August 30, 2009, he released a new single titled "Loca" also used as the main-theme for telenovela Los Exitosos Perez
and first single from his latest album. "Loca" reflects a reimaging of Robert Palmer's "Addicted to Love" music video.Syntek is credited with singing in the chorus for Somos El Mundo, a production by Latin American artists in order to raise awareness and inspire charity after the tragic earthquake in Haiti. He can also be seen in the music video.
After the release of Kylie Minogue's single "In my Arms", Syntek released his own official remix with added lyrics. This remix was released in early April 2008. The song became Minogue's highest charting single in Mexico at number seven since "Come Into My World" reached number one in 2003.
