Hi! I'm Jungmi.

I'm an accomplished UX designer with a proven track record in steering innovative products from concept to launch. My methodology is deeply rooted in understanding human needs, coupled with swift validation through comprehensive research and prototyping.

 

In my recent role as a Senior Designer at Roku, I was instrumental in the design of the smart home mobile app for iOS and Android, as well as the TV app based on Roku OS. Successfully navigating from ideation to market launch, I prioritized understanding customer needs and staying attuned to market trends, resulting in the successful deployment of multiple projects.

 

During my tenure at Lutron, I contributed significantly to the development and design of home and building control experiences within the IoT ecosystem. Leading a team of 4 junior designers, I gained valuable experience in orchestrating collaborative efforts for successful project outcomes.

 

With a decade-long dedication to the Samsung UX team before Lutron, I played a pivotal role in launching numerous products across diverse devices and platforms. My skill set spans the entire UX spectrum, from devising optimal scenarios and details through user research to the final product, always mindful of implementation and business goals.

 

An inherent passion for continuous learning drives me to stay abreast of new industry developments and incorporate them into my design work. I am committed to bringing a blend of experience, leadership, and adaptability to contribute effectively to the team and projects.
