I turn messy data into decisions that stick.

Senior Data Scientist with 5+ years at the intersection of people, behavior, and statistics. I've built attrition models, designed workforce experiments, and shipped ML systems used by executive teams. Whether the domain is People Analytics or Product Data Science, I bring the same thing: rigorous methods, clean code, and a clear story.

People Analytics & Workforce Intelligence Data Science & Applied ML

The Work Professional

I specialize in causal inference, predictive modeling, and experimentation, applied to domains where the stakes are high and the data is messy. My background spans People Analytics at Publicis Sapient and Korn Ferry, workforce intelligence at Infosys, and I'm completing an MS in Business Analytics at the University of Cincinnati (2026).

I can run a PSM analysis and explain it to leadership the same afternoon. I build things that actually get used: Tableau dashboards for executive reviews, flight-risk scores operationalized into retention playbooks, A/B tested sourcing strategies with documented causal impact.

Beyond the Data Personal

Outside of work, I box, and I mean that seriously. The discipline, the structure under pressure, the need to stay technical when you're tired. It maps onto data science in ways that still surprise me.

I hike whenever the Bay Area weather cooperates (which is often enough). I read broadly, organizational behavior, behavioral economics, the occasional novel. I've been a teaching assistant and mentor at UC, and genuinely enjoy helping people build the instinct for good analytical judgment, not just the mechanics.

Let's work together.

I'm actively exploring Senior Data Scientist and People Analytics roles where I can pair statistical depth with real business impact. If you're building something where the human data is as important as the product data, I'd love to talk.
