欣 宇

Hsin - Happiness also meaning interest or appreciate Yu - The world, universe, or outerspace

Together meaning to keep interest to the new world and as well as to enjoy the life of the present. I have enjoyed life to the fullest and given the best of myself during my living. Always in good mood with a sparkling personality. My education and experience so far has equipped me with the skills and confidence to face a wide range of design problems. I like the whole process, from getting into the mind of the consumer to presenting a refined, innovative solution. This portfolio shows a wide range of work, and hopefully proves that I am a creative thinker, with the ability to add intelligence to any designings.
