About the tiny man between the Giant Sequoias


I am Keith Tseng, a designer based in NYC. I design and prototype product and service to serve the people and hopefully the environment as well. Prior to the transition as a designer, my role was as a front-end developer. Even today, I believe there is no boundary between form and function as design and engineering tightly weaved together so I utilize the development skillset and knowledge of technology limitations to bridge the gap and bring the ideal design closer to reality. For my past experience, please refer to my resume.

In the process of solving challenges, I strive to be a liaison between the teams to collaborate and contribute through the understanding of user experience, designing and prototyping the intuitive interaction, iterating the flow and refining the interface. Design with thoughtful functionality, simple aesthetic and clarity mesmerized me.

Besides design, I love to enjoy nature, camp in the woods, snowboard in the mountains, train outdoor for sprint triathlon and rock climb in the gym. Learn more on Instagram.
