About

A data scientist and squad leader who builds digital solutions that transform healthcare manufacturing — driven by the belief that knowledge is the ultimate currency and meaningful work demands both technical depth and human understanding.

At Roche, I've progressed from building my first web application as an intern to leading cross-functional squads across four countries. Every step was driven by the same conviction: hard, meaningful work — the kind that helps patients — produces the most impactful results.

Philosophy

Principles I live and build by — inspired by thinkers I admire, tested through years of building systems that matter.

The ultimate currency in the universe is knowledge.

This drives everything I build — data platforms, dashboards, AI tools. Not just collecting information, but creating systems that generate understanding.

It's easier to work on a hard, meaningful project than a simple, meaningless one.

From ramping up COVID-19 testing production to digitally transforming manufacturing plants — hard problems give you more energy than easy ones.

Everything in this world has been created by people like you.

No gatekeeping. Ordinary people built everything extraordinary. Now it's our turn to create something that matters.

Team spirit wins.

Leading across four countries taught me this. The best systems are built by people who understand each other — not just the technology.
