About Leslie Leslie Yoon

I’m a Senior Product Analyst on Coupang’s Search & Discovery team, where I lead customer-centric evaluation and experimentation for AI-powered search and shopping experiences. My work spans search behavior analysis, customer intent modeling, and end-to-end quality frameworks for LLM- and multimodal (text + image) systems, partnering closely with ML, UX/UI, and engineering teams to improve ranking models, recommendations, and user trust at scale.Previously, I built a strong foundation in go-to-market execution through B2B strategy and IoT solution sales at Samsung Electronics. I hold an MBA from Cornell University, where I focused on digital technology, strategy, and analytics, and gained hands-on product marketing experience through an internship at Pure Storage.
