My path into art and design was never a straight line. It began with architecture in Korea—learning the disciplines of rigor, structure, and responsibility—but I kept returning to one quiet doubt: buildings become fixed, while people remain in motion. I could design containers, yet I wondered if architecture could ever truly hold perception—how a day feels, how memory shifts, how a room changes when a body enters. That tension became the seed of my practice: not to leave architecture behind, but to keep opening it until it can breathe. Los Angeles was my decisive turning point. Through postgraduate research at SCI-Arc, I entered a culture where systems, media, and computation are treated as raw materials—where an algorithm is not just a tool, but a form of authorship. Later, as a computational designer at UDI Studio, that curiosity met the hard discipline of making: our questions had to survive the friction of geometry, budgets, and time. Somewhere in that crossing, I stopped thinking of design as a career choice. It became the only honest way I knew to let a question take form. Today, I work in a self-sustaining loop across practice and education. I lead FLMT as a platform to test ideas against reality, and I teach digital architecture because teaching demands a rare precision—if I cannot explain a system clearly, I do not deserve to use it. MediumCloud grew from this same impulse: an educational archive for “research crumbs” and experiments, kept in plain sight, where the process is as important as the outcome. In the end, I design the way an artist composes: translating invisible structures—data, rules, time—into experiences that feel immediate, human, and alive.

FLMT stands for 'Feel a Moment.' It is both our name and our operating principle: in an era of constant stimulation, the most meaningful luxury is not excess—it is clarity. We design for the moment a person recognizes a space as their own: the exact weight of light on a surface, the silence between materials, and the way circulation becomes intuitive without explanation. That pursuit gives our work an artistic sensitivity, but we run the studio with a distinctly business-minded discipline—because atmosphere only becomes real when it survives the entire process of realization. FLMT is a multidisciplinary practice working across architecture, interior, and computational design. In our studio, computation is not a visual style; it is a method for making decisions legible—organizing complexity into systems that can be built, maintained, and experienced. We move seamlessly between conceptual authorship and technical accountability, treating both as part of the same design act. What differentiates FLMT is how we take responsibility for the 'middle zone' where many projects lose their essence: the space between a strong concept and a finished environment. We are fluent in the language of construction—value engineering without diluting intent, material testing, and rigorous site coordination—because this is where design either becomes precise or compromised. Our goal is straightforward: to protect the original narrative while making it buildable and operable. Perception Cafe is a prime example, where spatial storytelling and operational logic had to be perfectly aligned under real-world constraints. We work best with partners who look beyond a 'nice interior'—clients who care about brand longevity and the lived reality of space. The result we provide is not just a finished environment, but a repeatable method that can scale or evolve without losing its identity. Ultimately, FLMT treats design as translation: translating invisible structures—data, rules, behavior—into environments that feel immediate and quietly unforgettable. We keep the technology silent, using it only to make the human experience speak more clearly.

To me, design is the high-resolution calibration of human experience. It is not decoration; it is the rigorous act of proving that a question can survive the friction of reality. I often think of it as a bridge between the infinite freedom of code and the stubborn limits of matter, where intent must become measurable, buildable, and repeatable. In my practice, design is a form of technical accountability. We live within complex systems—data, networks, regulations, budgets—and my responsibility is to master those forces so they never overpower the human moment. I use computational logic not to perform complexity, but to distill it: to find a structure that feels intuitive, quiet, and precise. At its best, design makes technology silent so that experience can speak—through light, proportion, texture, sound, and time. If my earlier work was a 'license to question,' then design is the physical evidence that those questions were worth asking. It is how I stay awake in a world of clichés, translating the invisible rules of our era into spaces that people can feel immediately—and remember without effort.

I am most drawn to projects where the 'atmosphere' is not a decoration, but the core performance of the space—projects where an idea must be felt, not explained. I like work that treats perception as a material: light, reflection, refraction, time, movement, and the subtle shifts that occur when a body enters a room. These are the projects that demand both artistic authorship and business-grade precision, because the moment only becomes believable when it can be repeated every day under real-world conditions. This is why I gravitate toward flagship environments and immersive interiors—spaces that carry a brand’s philosophy without relying on signage or spectacle. They require an unusually tight alignment between concept, detailing, and supervision; even the smallest mismatch in tolerance or sequence can collapse the intended experience. For me, the most rewarding work is where poetry is engineered: when the emotional reading of a space is supported by a quiet, rigorous logic that remains invisible to the visitor. A definitive example is our project Linear Envelopes, a flagship space for BONOMONG in Itaewon, Seoul. The central ambition was to translate the essence of a forest—trees and sunlight—into architectural phenomena. We built a 'glass forest' and a trail of light where layered objects catch daylight and release it as optical caustics—a living pattern of sun that shifts through time. Rather than representing nature as a static image, we created conditions for it to reappear as an event: a choreography of reflections and moving light. I find the tension between the intangible and the measurable in such projects deeply energizing. It forces design to become accountable—an artwork that must operate. In the end, these are the works I love: spaces that are quietly technical, unmistakably sensory, and built to sustain a human moment with absolute clarity.

One of my most personal projects is our Samseong-dong business facility in Seoul, because it captures what I believe design must do at its highest level: remain bold, yet behave with restraint. The project began with a difficult question—how can a contemporary workplace assert its identity without becoming visual noise to the city? The site sits in a sensitive condition, bordered by residential edges on two sides. That reality became the project’s ethics. Instead of treating the façade as a cosmetic statement, we developed it as a calibrated envelope—a gradient system that negotiates privacy, daylight, and presence. As the building approaches the neighboring homes, the logic tightens: openings become more controlled and the surface shifts from expression to protection. In other words, the architecture doesn’t simply 'show itself'; it learns when to soften. I call this quality 'urban etiquette'—the ability of a building to participate in the city without dominating it. What I love most is that this project proves empathy can be engineered. Every fold and aperture is a measured response to context, not a stylistic signature. The result is a kind of quiet armor: a structure that performs as a business facility while shielding the everyday lives next to it. It is evidence that an architectural idea can be precise and contemporary while remaining deeply considerate. For me, that is the most enduring form of beauty: not what demands attention, but what earns trust over time.

The first thing I designed for a company was a computational envelope and façade system while working at UDI Studio in Los Angeles. It was my first real encounter with design as high-stakes authorship under constraint—where an idea is only as good as its ability to hold up against cost, fabrication logic, coordination, and schedule. My role was to translate an intent that began as pure geometry into a system that could actually be built: rationalizing curvature into producible families, establishing tolerance rules, and delivering outputs that could move cleanly from screen to shop to site. That experience shaped how I lead design today. I don’t use computation as a visual signature; I use it as a precision instrument that protects the atmosphere. The goal is not complexity, but inevitability: a space that feels effortless because the logic underneath is disciplined. In that sense, my 'first' wasn't just a façade—it was the moment design became executive accountability, where every aesthetic decision had to justify itself in performance, time, and money. If you’re asking about the first work under my own studio, FLMT (Filament LLC)—which I founded in June 2018—it wasn’t a commissioned project. It was a small pavilion proposal for a public park; a project we pursued out of conviction, almost like a private manifesto made public. We treated it as a concentrated experiment in perception: how light lands, how proportion holds silence, and how a simple structure can carry a distinct emotional temperature. That pavilion set the trajectory of my practice—from distilled spatial gestures to flagship environments where a brand must be felt without explanation. Today, FLMT operates at the intersection of authorship and delivery. We are a practice built around design implementation and supervision—supported by a digital pipeline that makes decisions traceable and buildable. We use computational methods not to showcase technology, but to keep the human experience consistent. In the end, my earliest 'firsts' taught me the principle I still work by: the most successful technology is the one that stays quiet—so the space can speak.
