Overview
As a core member of the software engineering team behind Amazon Style, I helped launch Amazon’s first-ever physical fashion store, reimagining in-store shopping through deep integration of digital technologies. The project focused on enhancing the customer experience through personalization, operational automation, and seamless online-offline shopping integration. I worked across the full stack — from Android-based retail devices to React-powered web interfaces — building smart fitting rooms, device management services, and scalable backend systems.
Amazon Style combined the convenience of e-commerce with the immediacy of physical retail, leveraging customer preferences and machine learning to recommend outfits, streamline try-on processes, and provide real-time item availability.
