I’m a freelance sound designer specialized in sound design for video games and animation. Over the years, I’ve worked on multiple student and independent animation projects from schools such as Gobelins, ECV, RUBIKA, and ESRA. Some of these films were selected for and won awards at international festivals, where I handled the full sound design and final mix in both stereo and 5.1 formats. I mainly work remotely, but I also have the possibility to do final mixing sessions in a professional studio if the director would like a more precise and cinematic listening environment. I’ve worked on several mute animated short films, including projects centered around the Spanish Civil War as well as more comedic productions. My goal is always to highlight the animation through sound, enhancing both emotion and timing while supporting the visual storytelling as naturally as possible. I pay particular attention to ambience and environmental detail, which is a subject I explored deeply in my end-of-year thesis focused on sound atmospheres and immersion. Alongside sound design, I also play guitar and enjoy editing and integrating music so it flows naturally with the scene and interacts dynamically with the sound design itself. I would be thrilled to contribute to “Thera: The Inverted Planet” and help bring its musical and animated world to life through immersive and expressive audio.
