Hello, I‘m Kisoon Kwon, and I’m a software developer with 10 years of experience.
My interest in video and audio content led me to pursue the development of multimedia software.
Through providing technical support to clients in the US and Europe, I gained knowledge of various media-related topics and trends.
To ensure fast and accurate solutions, I make a habit of analyzing and sharing information.
I strive to approach things from diverse perspectives, whether it be something small or exceptional.
