About

Technical UX Designer for audio tools, engineering software, and technical documentation. From senior pro-audio support at Apple, to sole designer at Valispace (acquired by Altium), to Web Audio API contributions at MDN.

One question runs through the work: what happens in the space between humans and technology — verbal, non-verbal, auditory. Audio-only tech support, engineer interviews, interface design. Different surfaces, same inquiry.
