I’m a Chilean Audio Engineer, Music Producer, and Session Musician with over 15 years of professional experience in recording, mixing, mastering, and live sound. I’ve been a musician since the age of 14, performing as a guitarist and bassist in several bands and recording sessions, always composing and arranging original music. This strong musical foundation gives me a refined ear for tone, dynamics, and emotional storytelling through sound. I’ve worked extensively in amplification and live sound reinforcement for bands, solo artists, corporate events, and concerts ranging from small venues to large-scale productions. My experience covers both studio and live environments, allowing me to approach every project with technical precision and creative sensitivity. I’ve also worked as a session guitarist and bassist, collaborating with artists in different genres and providing arrangement and production support. To specialize in narrative and interactive audio, I am actively strengthening my skills in this field. My portfolio currently includes three musical compositions prepared for video game integration, and I am actively studying FMOD to master implementation and workflow. Furthermore, I have received advanced vocal training through the International Dubbing Course (BioVoz Chile). I’m proficient in Pro Tools, Studio One and hold Pro Tools User and Specialist certifications. My combined background in engineering, musicianship, and production allows me to craft clean, balanced, and emotionally engaging mixes that elevate visual and musical storytelling.
