Motivation

What drives me

US Healthcare Complexity
Fragmented systems, high stakes, real patient impact. Exactly the kind of problem worth dedicating years to.
Clinical Intelligence
Connecting HCPs, trials, publications, and pharma signals into something actionable for the people who need it.
Infrastructure that lasts
Fast, reliable, and maintainable. I care about the long-term health of systems, not just shipping.
Governance & Trust
Data you can trace and defend — especially when the stakes are regulatory and quality matters.
