I am Hieu Nguyen Phi, FRM, a Quantitative Risk Analyst from Ho Chi Minh City, Vietnam. I have a background in International Finance by Foreign Trade University. I have also charterred the FRM certification by [GARP](https://www.garp.org/#!/home) since 2018, after 2 years of experience in Risk management in banking and investing sectors. I also inspired by Mr Sheldon L. Cooper, a fictional character in the CBS television series The Big Bang Theory. He is who he is and doesn't pretend to be someone he isn't. He is so serious about anything he's doing, from academic tasks to real-life businesses. With my inherent laziness, I always look for the best and most efficient (in terms of time and my energy capacity) approach to resolve my practical issues. Currently, I am employed by [Viet Capital Bank](https://www.vietcapitalbank.com.vn) as Risk Analyst and Modeler. My responsibility is to build risk models and to perform required analyses for the bank's Credit Risk Portfolio.
