About Yoon

Bonjour! I'm Yoon from South Korea.

I am a Product Designer and UX Researcher specializing in the intersection of human psychology and complex technical systems. My approach is defined by a unique career trajectory that began with analyzing neural signals in brain-research labs and evolved into engineering high-stakes Instrumentation and Control (I&C) systems for nuclear power plants. This background allows me to approach design not just as an aesthetic challenge, but as a cognitive one. I specialize in transforming dense, multi-layered data into intuitive digital experiences, ensuring that even the most sophisticated systems feel natural and accessible to the user.

My recent work has focused on the frontier of "Spatial UX," where I lead the product development of Digital Twin ecosystems. By integrating my Master’s research on Social Presence and Proxemics, I design virtual environments that respect human spatial intuition and enhance telepresence. Whether I am architecting a 3D interface for industrial monitoring or developing a user-centric VR simulation, my goal is to reduce the friction between the user and the technology. I thrive in environments where precision, safety, and human behavior must align perfectly.

Relocating to Lyon, France, this August, I am eager to collaborate with forward-thinking teams in the European tech scene. Beyond my technical work, my current role as a tennis coach at JTA has instilled in me a deep sense of sportsmanship and the ability to communicate complex concepts with simplicity and patience. I offer a rare blend of rigorous engineering discipline and a collaborative, creative mindset. I look forward to helping partners in France build the next generation of immersive and functional digital products.
