01 / About

I ship real-time systems that meet their deadlines.

I've shipped radar DSP software, a new receiver architecture, and an automated photolithography controller presented at AAAS and NCUR. What they share is unforgiving timing and data crossing hardware boundaries at the byte level. Systems like that fail in the field unless robustness and performance are designed in together. I'm looking for principal or lead roles in DSP, embedded, or systems work.

  • Profile real-time paths before I touch them
  • Define interface contracts before teams depend on them
  • Hold user and operator experience to the same standard as my own tools
  • Build the dev environments and pipelines I would want to inherit
