I am a Malaysian Chinese born in Sibu, Sarawak, a state of Malaysia. I work in Kuching, which is in the same state, as a civil and structural constulting engineer. Kuching is a beautiful small city with lots of trees and landscape along the streets. My interests are computer, programming, engineering, mathematics and physics.
