Building what I wished existed yesterday

Technologist, founder, T1D advocate. Fifteen years shipping software. Building AI for behavioral health that actually works.

Started at 14. Still building.

Hospital networks at 16. VoIP and M365 rollouts in my twenties. Data center ops. Then in 2021, co-founded Nextvisit AI with a psychiatrist who lives the documentation problem. I keep ending up at the intersection of healthcare and software that has to not break.

Living it, building for it, fighting for it

I have Type 1 Diabetes. It isn't the kind you fix with diet or exercise. My pancreas stopped making insulin, and without 24/7 management, things go sideways fast.

That changes how I build. I've seen the math from the patient chair: people die when they can't afford the medication keeping them alive. Healthcare tech should give people more life, not just move paperwork around faster.

  1. 01
    DIY Loop community

    Active in the open-source movement building DIY closed-loop insulin systems.

  2. 02
    Breakthrough T1D Walk

    Walk the Westchester event every year to raise awareness and money for T1D research.

  3. 03
    Insulin access

    Pushing for better access to medication that people literally need to stay alive. I run Omnipod Dash with DIY Loop myself.
