Forward Deployed Data Scientist

Most data scientists hand off work. They build in notebooks, present in slides, and watch from a distance as their models meet reality.

Forward Deployed means I'm in the room when reality pushes back.

The Climb

Senior Manager, Data Science

At Teladoc Health, I lead teams building AI that shapes real clinical decisions — at scale, in production, with meaningful stakes.
Not a proof of concept. Production.

V
Data
Identify patterns, separating critical signals from noise
Deliver personalized, "just-in-time" interventions
Validate with real-world outcomes at scale

The Philosophy

We're past the age of building for humans alone.
Every system I design is legible to both — human intuition and machine reasoning. That's not a technical choice. It's a worldview.

Every week, I publish an interactive essay where data meets philosophy, and code meets the questions ordinary life hides in plain sight.

Not tutorials.
Not hot takes.

What’s Left?

Time doesn't disappear slowly. It disappears in weeks — unnamed, uncounted, unremarkable. Until you count them. Then nothing is unremarkable anymore.

What’s Left turns age into a map of time: sleep, work, seasons, friendship, parents, and the hours that remain.
