Building technology that serves people. Documenting the people technology forgets.

Builder

I build companies at the intersection of healthcare and artificial intelligence. As CEO of Holman and founder of Lifetria, I work to close the gap between what clinical science knows and what patients actually receive — using machine learning to make diagnostic precision accessible, not exclusive.

The hardest problems in tech are rarely technical. They are human. Organizational. Cultural.

Operator

Before that, I spent years scaling enterprise technology across three continents, learning that the code is the easy part. The real challenge is aligning people, navigating organizational complexity, and building cultures that can sustain ambition.

Witness

In parallel, I photograph. Conflict zones, displacement camps, communities on the margins of geopolitical attention. The camera is my way of bearing witness — of insisting that the people most affected by the systems we build deserve to be seen, named, and remembered.
