About

Hi I'm Joel! My first app is an iOS app to help poor conscripted army servicemen in Singapore countdown to the end of their service. It actually got pretty popular. I then developed a passion in frontend web development and have a little obsession with user interface design. In my free time I make YouTube videos, play the drums and try to dance.
