Hi, I'm Leon. I recently graduated from Ohio State University and am now pursuing a Master of Computer Science at UIUC. During my time at OSU, I served as an undergraduate TA for the operating system class. After graduating, I gained valuable experience through two internships. Firstly, I worked remotely for a startup in San Francisco, where I developed the backend for their first MVP. I successfully handled features such as user registration and login by my own, including unit and integration testing. Additionally, I interned as a Machine Learning Engineer at Shanghai Artificial Intelligence Lab. There, I achieved a 20% reduction in training time and a significant 30% decrease in Mean Absolute Error (MAE) for an Adaptive Prediction Model. I also created a controllable text-generation chatbot, which was adopted by the State Grid Corporation of China. I am now the team lead of advanced database class and familiar with data cleaning and feature engineering.
