Gibson Tang

Gibson Tang grew up loving technology after getting his hands on an old Apple II when he was still a young kid. Since then, he has never stopped keeping pace with technology, and after he coded his first "Hello World" program, he has been hooked on programming ever since.

Following his studies at Nanyang Polytechnic and Singapore Institute of Management and serving a 6-year stint in the Republic of Singapore Navy (RSN), he honed his development skills creating software and games for Yahoo! and other Fortune 500 companies. In 2010, he founded Azukisoft Pte Ltd in Singapore to focus on mobile application development. Since then, he has developed countless mobile applications and games for start-ups and big companies both in USA and Singapore.

Apart from programming, he indulges in various hobbies such as soccer, computer games, and jogging in order to get his regular dose of Vitamin D and to see the sun once in a while. Occasionally, he would be on Steam or Battle.net blowing off some steam by slaying monsters and killer robots after a day of programming.
