About

An accomplished leader in product management with over 10+ years of global experience. I excel in guiding products from concept to launch, turning innovative ideas into market successes. My expertise is rooted in over five years of experience at Rakuten, where I’ve led the strategic development and scaling of consumer-focused products, including the pioneering Rakuten Link mobile app, Symworld platform and digital transformation of Rakuten Ichiba - Japan's biggest B2B2C eCommerce with over 50K merchants and 100M users. My skill set is a unique blend of product management and user-centric design, ensuring that each product not only fulfils market needs but also provides a seamless user experience. I am also a top-tier mentor at ADPList and a recognised speaker at industry-leading events like Mind the Product, Product Tank in London, and nurturing the next generation of product leaders and advising upcoming startups.
