Senior Product Designer at WPP who shipped Discover Audiences features and a conversational Persona agent.

At WPP, I led Discover Audiences design across three development teams, from discovery to delivery. I shipped features that cut research time for planners and strategists, and launched a conversational Persona agent based on direct user requests.

At WPP, I co-designed the AI layer with Data Science, defining quality criteria and grounding outputs in partner data to address users’ trust concerns. Before that, at Wavemaker, I designed five internal media apps for a combined 5K active users and created a shared component library.
