I led product research and design at Clyx from beta to a $100M valuation, driving a 75% increase in content creator conversion and a 53% uplift in D30 retention. I built FiFi, an AI-powered fashion discovery app turning short-form video into high-intent e-commerce. At Reewild, I translated behavioural insights into product strategy, defining its series-A roadmap.
