About the Composer

I have dedicated my entire life and soul to music, especially film music. My cinematic versatility stems from countless hours spent listening to and admiring the soundtracks of numerous films and from the many projects, from short films to feature films and video games, that I have had the pleasure of working on.

Specializing in film music, I began my studies independently and self-taught, eventually gaining direct access to the Master’s program in Composition for Audiovisual Media at the Katarina Gurska Higher School of Music in Madrid.

Subsequently, I received a scholarship to pursue a Bachelor’s degree in Film Music at the Film Scoring Academy of Europe in Bulgaria, where I trained with internationally renowned professionals such as Norman Ludwin, orchestrator for Michael Giacchino and double bassist for John Williams, among others.

I have received nominations and awards at various festivals and competitions, including the 2023 Film Music Contest, the 2023 European Recording Orchestra Competition, the Best Music for Short Film award at L’HIFF 2020, and the 2024 Almagro International Film Festival.

Under the premise that “music is the inner voice of the image,” my work seeks to express and give voice to the visual through a wide range of styles, from symphonic orchestration to minimalist composition, including synthetic and experimental productions.
