I had the pleasure of being Zheng's team lead during his time as a Data Scientist at SimpleBet. As a data scientist, Zheng demonstrated his proficiency with Python and associated packages such as scikit-learn, pandas, matplotlib, and NumPy on a daily basis. He wrote scripts to evaluate the runtime efficiency of his code as a function of the input size, and also created unit tests for his code using the pytest module. He also helped me architect and implement a comprehensive in-house data visualization module, and offered creative ideas along the way to make the module more flexible and convenient to use. In closing, I recommend Zheng without reservation for any positions that might require the skills touched on above. He is a pleasure to work with, a team player, and self-motivated. He is an asset to any endeavor he chooses to pursue!

It has been a pleasure working with Zheng. He came to the business with no pharmaceutical knowledge and quickly transformed himself into a go-to resource. He has an eager curiosity to dig into the subject matter and understands what he is working on in depth. This is made him a valuable resource for his teammates as he helped to implement processes into the group while his knowledge of database systems allowed the business operate much more efficiently. His steep learning curve and advanced knowledge of technical tools and programming making him an excellent dual talent to any business.
