WONG ZI AO

I'm a Bachelors degree I.T graduate from MMU University specializing in Business Intelligence and Analytics. It is my passion to derive and discover insights from unknown problems into known, and transfer them into workable solutions. I've also developed a keen interest in working with people. As I always believe: "People is always the key to organizational success, while technology serves as a valuable tool and accessory to help achieve goals."
