About

I'm an audiologist working with Research, Development, and Innovation at Eikholt. My work focuses on audiovisual speech understanding, accessibility, and innovative technologies.

I build things across the stack - from embedded systems and hardware prototypes to web applications and AI tools. The projects above mix professional research work with personal hobby projects.
