Crafting digital experiences where ideas, strategy, and code intersect

reemarc | Connected Dental Care Journey

[UXUI] [B2C] [Mobile App] [Startup]

reemarc is an early-stage digital healthcare startup and consumer mobile app that connects patients with trusted dental clinics worldwide, making high-quality care more accessible, personalized, and seamless through technology.

I led the end-to-end design of the consumer app, defining the core user experience, patient–clinic communication flows, and foundational product structure from early development through launch.

Smile Solutions | Dental Clinic Management Portal

[Product Design] [B2B] [SaaS] [Startup]

Smile Solutions is a web portal that enables dental clinics to manage patient treatment progress and communicate with international patients throughout their care journey.


I inherited an early beta with fragmented patterns and underdeveloped workflows, then restructured the product based on user interviews and operational review to make it more consistent, usable, and ready for real clinic use.

People Watching | Interactive Installation

[Experience Design] [Immersive Storytelling]

People Watching explores the unseen stories carried by ordinary people moving through everyday life. Through touch- and proximity-activated silhouettes, the piece reveals intimate filmed narratives that invite viewers to look beyond appearances and connect with the emotional worlds of strangers.


I led the design of the project from concept to execution, shaping the interactive experience, narrative framework, and physical installation in collaboration with engineers and through custom-built sensing technology.

I’ve been exploring design through storytelling, visual design, and web development for the past few years. Having grown up between Korea and Canada, I’ve come to value different ways of seeing, communicating, and relating to others. As a designer, I care about shaping digital experiences that feel simple, intentional, and human, with thoughtfulness in both the big picture and the smallest details.


Outside of work, I spend time with my dog Eve 🐶 and stay close to music 🎻. I also played in orchestras for many years, which continues to shape the way I think about rhythm, harmony, and collaboration.
