What I'm looking for

Seeking a challenging role that leverages my expertise in iOS development to drive innovation and excellence.

I love to design and develop iOS applications that can bring smiles on people's face, and enjoy creating pixel perfect UI/UX and users love using it once after another.

I created my personal iPhone app to help me tracking my expenses. And I'm the primary user and tester of the app. Constantly modify and enhance the app every time I spot something or some place is not convenient.

By pushing beyond limits, I intent to be as picky as possible, the goal is to build the app seamlessly smooth and let any user falling in love with it after first time using it.
