About
Boston bred, building in San Diego.
I built ToneAdapt in 2025 for guitarists who want to sound like the record on the gear they already own, and it took off. Now I'm building Raze Labs with Ian Carscadden.
Before that: ML at Amazon, and computer science at San Diego State until I dropped out to build.
