Senior product manager with 10+ years of experience building AI-enabled and consumer-facing products across connected devices, mobile apps, and digital health. I specialize in turning ambiguous spaces into clear strategies and shipping customer-centric features that drive meaningful improvements in growth, engagement, retention, and revenue.

Selected wins: delivered double-digit conversion improvements; launched new customer experiences that significantly outperformed growth baselines; exceeded customer satisfaction goals during beta; scaled digital health communities to top App Store rankings; cut acquisition costs by 85%+ in fintech; and built the analytics and operational frameworks that accelerated team velocity and decision-making.
