My name is Yun-hyeong Kim. I have worked in the Graphics R&D Group at Samsung Electronics. In Samsung Electronics, I wholly contributed to the animation tasks of the AR Emoji app exclusively made for Samsung Galaxy by working on its animation pipeline design, integration of retargeting solutions, and performance optimization. Before joining Samsung, I have studied physics-based animation and mesh unfolding in the fields of Computer Animation and Computational Geometry to obtain a master’s degree at Ewha Womans University.
Through my 4 years’ experience in research, I built up base skills such as problem identification and problem-solving. In addition to that, my experience with Samsung gave me skills in agile software development along with close and active collaboration with other engineers from external companies. These experiences and skills have led me to improve my abilities in analysis, architecture, and optimization.
As a software developer and a researcher, I love to share ideas, solve problems, and develop programs. My fulfillment comes only after finishing tasks with desired results.
