CTO & Co-founder, Nextvisit AI New York, USA

Healthcare software that holds up.

CTO and co-founder of Nextvisit AI. I write software for behavioral health, clinical documentation, and the parts of care that fall apart when the tooling is lazy.

I learned infrastructure before I learned polish.

I started with websites, then got pulled into hospital networks, VoIP migrations, M365 rollouts, and data center operations. In 2021 I co-founded Nextvisit AI with a psychiatrist who had spent years losing evenings to documentation. The common thread has been healthcare software where failure is not theoretical.

Type 1 Diabetes changed how I read healthcare claims

I have Type 1 Diabetes. It is not the kind you fix with diet or exercise. My pancreas stopped making insulin, and the management never clocks out.

That changes how I build. From the patient side, healthcare is not an abstraction or a workflow diagram. It is the cost of insulin, device access, alarms at 3am, and whether software gives clinicians enough attention to catch what matters.

    Insulin access

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

Healthcare tech, T1D, open source, a technical problem worth thinking through. A clear note is enough.
