I have been mastering records since 2010. Throughout my career, I have had the privilege of working with both major and independent labels, collaborating with emerging artists as well as established acts across a wide variety of genres.

I am a founding member of Estúdios Sá da Bandeira, Bender Mastering Studio and Arda Recorders, where I established my studio early on. I am also the founder of Knurl Mastering, where I currently work.

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.
