Apart from being a web developer, I enjoy most of my time on video games to find inspiration. Beside, I do enjoy problem analysis and solving which give me lots of satisfaction, that's why I also one of the chess lover.

I am a curious person, although "curiosity killed the cat, but satisfaction brought it back". I do believe curious will push me further and I spend a large amount of my free time exploring the latest technology and advance my personal skill set.
