background
I'm an audio plugin developer and DSP engineer with deep experience in JUCE/C++20 real-time audio. My background spans commercial plugin development (Althemi/Studio369), startup co-founding (Ethereal Computing), and applied music AI research.
I work at the intersection of three things most people treat as separate: low-level signal processing, music as a perceptual and creative medium, and modern machine learning. The interesting work lives in the seams between them.
