About Zijin Cui

Hello! I\'m a graduate student at Carnegie Mellon University, specializing in Business Intelligence and Data Analysis. I earned my Bachelor\'s Degree from CUHK Shenzhen in Data Science and Big Data Technology. As a highly motivated aspiring data scientist with a strong foundation in machine learning and data analysis, I have honed my skills through hands-on experience as a Research Assistant and Intern Data Scientist. At the Chinese University of Hong Kong, Shenzhen, I collaborated with a talented team to predict diseases using multi-modal data, employing advanced machine learning techniques like Random Forest and SVM. I also designed and applied a transformer self-attention layer to enhance model accuracy, achieving significant improvements. During my internship at China Merchants Bank, I engineered a target customer detector for a flash loan product, achieving impressive results with an AUC of 0.81. My work in feature engineering and model evaluation doubled sales volume compared to traditional methods, showcasing my ability to drive impactful business outcomes. I\'m seeking a summer 2025 internship as a data scientist or machine learning engineer. I\'m eager to leverage my skills and contribute to innovative projects.
