About

I am a seasoned software engineering leader with 14 years of experience driving innovation and delivering impactful solutions at scale. Currently, I lead the Fulfillment Optimization team at Coupang, where we power the data science behind the fulfillment of Coupang's $30B customer orders, ensuring seamless delivery and operational excellence. Previously, I led transformative initiatives at eBay, including enhancing the View Item Page recommendations and building internal enterprise search capabilities using Large Language Models (LLMs). My focus has consistently been on leveraging cutting-edge technology to solve complex problems and improve user experiences. Beyond my corporate journey, I have entrepreneurial experience as the founder of Mobolt, a company that revolutionized recruitment technologies and was successfully acquired by Indeed.com. I thrive at the intersection of data science, engineering, and leadership, and I'm passionate about scaling teams and technologies to create measurable business impact.
