Hi all, my name is Chris Raharja. I graduated from University of Washington with BS in Mathematics. I used to work as a technology consultant in one of Big 4 firms and now I have been running several different business models such as print on demand, affiliate marketing, drop shipping, ads traffic arbitrage. I have been always passionate about teaching since my first time as a volunteer math tutor in high school. My goal on Udemy is to share my knowledge and build a wonderful community to study many different things together.
