emcodec

A neural audio codec that preserves the high frequencies other codecs destroy. Where Meta's DAC produces noise above 6kHz, emcodec faithfully reconstructs the signal.

Claude Code Plugin

Contract-driven autonomous goal execution for Claude Code. A subagent judge gates completion against an explicit Definition of Done, so a passing validator can't ship a placeholder.

About

Audio Software Engineer.
MS Data Science (Expected June 2026).
BS Audio Technology.

I work across the full depth of audio software, from ARM firmware and real-time DSP to neural networks and web applications. Everything I build starts with the same question: does this make a musician's life better?
