Hello,

I'm Fei(Sophia) Zheng.

About Me.

Simply love coding and data.


I am super passionate about solving problems by science and technology. I am strong self-motivated quick learner and I love to keep things organized. I have my own way of organizing and digesting knowledge and apply it across disciplines.

Currently I'm living in Vancouver and working in Workday Media Cloud team. My interests in computer science area are in software design and computer vision. I'm a frequent visitor to Udemy, Coursera, Lynda, InfoQ to keep my knowledge to up to date. But I am not entirely geeky, since I also love to play video games, reading novels, build hand crafts and play Chinese classical music instruments in spare time.
