Built for the
real world.
From the first conversation to systems built to scale. A few places where I helped turn ambitious ideas into working products.

I joined as the first hire, building real-time speech and video systems for realistic healthcare training conversations.
Explore SimCare workFrom voice commands
to conversations.
In 2021, I built Hola, a Python voice assistant for searching the web, playing videos, and handling everyday tasks with spoken commands.
Today, I build real-time AI infrastructure at SimCare, bringing speech, language models, and video together for live conversations.

Serious about
the work.
Curious about
everything.
I like chess, patterns, and thinking a few moves ahead. Take a shot at goal, explore somewhere new, or put a record on. Good ideas need a little room to play.
