Jinghan Wang

iOS Developer
Photographer & Art Quester

Majored in Computer Science with minor of Interactive Media Development (jointly offered by School of Computing and Faculty of Arts and Social Sciences)

I am currently an undergraduate student in the National University of Singapore, School of Computing, Department of Computer Science. I am pleased that one of my works has supported 9 languages, serving over 45,000 users around the globe and bringing them convinience in the real life.


I Got The
Skills & Expertise

I mostly work around with the iOS devices. From iPhone to iPad to Apple Watch, from iOS 5 to to iOS 7 to iOS 10, from Objective-C to Swift, with my experiences in dozens of major updates of the iOS system, I'm proud and happy to say:

I'm still up-to-date :)

Besides the sweaty coding work, I have touches on the UI/UX as well, including icon and layout design. My focus is in front end, and my expertise always acts as the smooth link between the UI designers and backend programmers.

Hand-draw artworks

Not just a programmer. I enjoyed my life via another way.
All these works are drawing with an iPad, expressing my feelings and thoughts at the specific moments, and possiblely with a story behind.

My Photography

Sometimes, what the cameras catched,
is not as simple as a picture.
It is the fourth dimension of life: your feelings at your time
