I'm Youjee, a multidisciplinary designer and former co-founder who completed my master's degree at Ewha Womans University. I am passionate about sustainable design. My first business was especially meaningful because it was also the first time I directly communicated with users, observed their reactions, and continuously improved the service based on their feedback. The more effort and thought I put into it, the more clearly I was able to discover better directions. Through that experience, I developed the habit of thinking from multiple angles and learned to give my best in every moment, no matter what I was working on. Through experiences, I have developed a deep interest in human attention and focus, which naturally guided me toward cognitive psychology. Understanding how the brain supports thought and perception is really fascinating for me, and I have continued exploring this through projects. This portfolio is an extension of my notes. After much consideration about how to share my experiences and projects well, I decided to build this website. It is still evolving, and I will continue to update it. Looking ahead, I hope to contribute by studying how humans and technology interact—and by creating sustainable value through thoughtful, human-centered design. <br>
