I'm an audio plugin developer and DSP engineer specialising in real-time audio. My work spans commercial plugin development (Althemi/Studio369) and startup co-founding as Head of DSP at Ethereal Computing, building the signal-processing and feature-extraction layers that turn raw signals into structured data. I'm also measurement lead on a biosignal pilot study at a teaching hospital, applying the same real-time signal-processing work to clinical movement data.
