I’m a Principal Product Manager who gets energized by turning messy data into decisions people can actually act on. My recent work focuses on applying data and AI in practical ways—helping healthcare organizations save money and improve care without drowning teams in dashboards.I’ve led products that- Drive adoption: Grew analytics products into enterprise insights platforms with 85%+ retention and an 86 NPS- Create real cost impact: Replaced brittle, Excel-heavy workflows with scalable benchmarking and procurement tools- Reduce operational friction: Built self-serve platforms now powering 40+ internal and customer-facing applications- Start with real-world insight: Shipped mobile experiences rooted in firsthand customer observation, not assumptions.At my core, I’m curious about what customers are really trying to solve, intentional about building for what’s next, and happiest working with cross-functional teams to deliver products that earn their place in people’s workflows.
