Mastering

My work as a mastering engineer

I have been mastering records since 2010. Over the years I've worked with major and independent labels across many genres, mastered records that went on to be nominated for Latin Grammy Awards, and collaborated with artists from newcomers to established acts.

I am a founding member of Estúdios Sá da Bandeira, Bender Mastering Studio and Arda Recorders. I am also the founder of Knurl Mastering, where I'm currently mastering records at.

Studio Design

My work as a studio designer

My design work spans from large-scale recording facilities and multi-room complexes to critical listening environments for mixing and mastering. Beyond the music industry, I work in industrial acoustics, applying these principles to the design of products for brands in other sectors.

Beyond the studio, I am active in audio education and publishing. I have taught at various colleges and specialized schools, covering both the technical and musical aspects of production.
