About
I’m a product designer with experience designing and improving digital products used across global markets.
My work sits at the intersection of user experience, product strategy, and business goals — from identifying friction in existing experiences to shaping new product concepts, experiments, and design systems.
Over the past several years, I’ve worked across rewarded advertising, mobile products, growth experiences, and internal product platforms at Tapjoy, ironSource, and Unity.
