Designing the systems
for 3 billion conversations
I'm a staff product designer at WhatsApp, with ten years of experience leading 0-to-1 and 1-to-many work across consumer, commerce, mobility, and social media platform products. My recent focus has been on WhatsApp's integrity and business experiences, shipping work used by over 3 billion people.
Originally from South Korea, based in London, and finishing a part-time MBA at Imperial Business School in 2026, which keeps my product thinking close to business strategy and leadership.
