01 — About

Background

I'm a software engineer who cares as much about the shape of a system as whether it ships on time. At Liberty Mutual, I lead the design and implementation of telematics data ingestion and scoring — the systems that turn raw driving data into something a business can act on.

Alongside that, I co-founded Overmild, where I lead engineering — from architecture decisions down to the CI pipeline.

Building Overmild

Alongside my work at Liberty Mutual, I co-founded Overmild, where I serve as Co-Founder and Technical Lead. I drive the technical vision — from early architecture bets to the systems that let us ship quickly without breaking things.
