ABOUT ME

I am a Mobile UX Designer at Samsung Electronics, where I focus on shaping the future of multi-AI agent experiences across Galaxy devices. My expertise lies in bridging cutting-edge AI platforms—such as Google Gemini, Perplexity, and Copilot—with Samsung’s One UI design language to deliver seamless, multimodal, and personalized user journeys.

Recently, I have collaborated closely with the Google Gemini UX team to implement cross-app action flows for Galaxy S25, enabling more intuitive and fluid interactions across multiple services. In this role, I defined and optimized critical user journeys that enhance engagement, and proposed UI designs that harmonize Gemini with the broader Galaxy ecosystem.

I am also leading the design adaptation of Gemini UX across diverse Galaxy form factors, including the Galaxy Watch 8, Galaxy Z Flip, and hearable devices, ensuring that AI-driven experiences feel natural and context-aware across different screens and interactions. In parallel, I authored and presented design proposals for multi-AI agent integration, laying the groundwork for partnerships with leading AI players such as Google, Perplexity, and Copilot.

My design philosophy is rooted in the belief that AI should feel invisible yet indispensable—anticipating user needs, reducing complexity, and creating experiences that feel effortless and personal. Through my work, I aim to advance Samsung’s vision of Galaxy-optimized AI UX that is not only technologically advanced but also deeply human-centric.
