Building technology that serves public health.

Chief Analytics Officer leading data strategy for 90,000+ patients across New York City. Native macOS developer shipping privacy-first tools on the App Store.

Where data meets purpose.

Over 17 years building technology solutions across healthcare and public health in New York City.

I'm a C-suite healthcare executive and epidemiologist who writes production Swift and ships apps on the Mac App Store. My career has been defined by a single thread: using technology to solve problems that matter.

As Chief Analytics Officer at Urban Health Plan, one of New York State's largest federally qualified health center networks, I lead all analytics and epidemiology functions for a patient population spanning the Bronx, Central Harlem, and Corona, Queens. I've built on-premise BI infrastructure from scratch, pioneered AI-driven clinical intelligence tools, and been activated for the city's response to Ebola, COVID-19, and M-Pox.

Outside of work, I build native macOS applications - privacy-first developer tools and utilities, written in Swift, with zero telemetry and no subscription bloat. My app devPad reached #1 in paid developer tools on the Mac App Store.
