Apart from being a software developer, I enjoy most of my time drawing digital arts and watching Japanese mangas and animations. I'm fond of the fascinating visual impact the artists can create with just one simple pencil.

Aiming to develop my own indie game in the near future, I'm also spending my spare time in learning game programing and 3d modeling/rendering, etc.
