Software Engineer in Test who enjoys designing hardware and embedded systems

I test streaming software for a living and build synthesizers in my own time.

Test Engineering

Seven years automating and certifying releases, most recently for the ad services behind Disney+, Hulu and ESPN.

Embedded Systems

Firmware, audio DSP and circuit board design, mostly on synthesizers and other instruments I build for myself.

Personal projects

Custom Digital Synthesizer

A handheld synthesizer I designed and built from scratch, starting with the circuit board and working up to the firmware. It has a grid of keys for playing notes, a pair of encoders for moving around the menus, and it can load and play samples off an SD card.

  • KiCad
  • C++
  • ESP32

ReclaimSpace

A Mac app for clearing out the things developer tools leave behind, like package caches, old toolchains and stale build folders. It tells you what each item is and how risky it would be to delete, and holds onto anything you remove for a week in case you want it back.
