My name is Taihua Li (Ty-hu-ah Lee), and I go by Ray. I am a Sr. Manager at Discover Financial Services (DFS), at where I lead a team of scientists to grow the DFS credit card portfolio. I also advise internal strategy, product, and engineering teams on scalable ML strategies and implementations. My top 3 expertise in the field are as follows,

• AI/ML and digital transformation strategy using cloud
• Data science model development and operation
• Scalable machine learning operations (MLOps) architecting

    When I was in college, I LOVED how economic theories and models explain real-world phenomenon. However, I was puzzled by how economists came up with the mathematical models, which led me to study econometrics and eventually to study machine learning. What machine learning attracts me the most is its ability to discover patterns in data using intuitively simple methodologies, and sometime without SME knowledge. I am also fascinated by how AI/ML help organizations evolve and innovate their processes, services and products, which directly or indirectly impact how we live our lives.

    I am from Quanzhou, Fujian Province, China, and my Chinese name is 李泰华. In Chinese culture, signatures can be represented in several ways, one of which is called a seal. The seal on the left is one way to represent my name, where the character on the right is my last name, 李 (Li), the top-left character is 泰 (Tai), and the bottom-left character is 华 (Hua).
