What I'm looking for

I seek a collaborative analytics role where I can turn data into product and operational improvements, use statistical methods, and grow in cross-functional leadership.

I am a results-driven business and data analyst with hands-on experience in KPI development, fraud detection, customer segmentation, forecasting, and A/B testing. I translate complex data into actionable strategies that drive measurable business outcomes.

At AI Whoo, I analyzed behavioral and traffic data for several hundred users, built segmentation using K‑Means and PCA, managed end-to-end A/B testing, and created Tableau dashboards that contributed to a 12% uplift in course completion rates. I bring practical experience deploying statistical rigor and visualization to influence product and UX decisions.

During a capstone engagement with Fender, I integrated internal sales data with external indicators, built SARIMA forecasting with polynomial trend adjustment to reduce forecast error by 7%, and recommended seasonally aligned marketing and operations strategies. At China Everbright Bank, I validated transaction records, analyzed 5,000+ credit card transactions using SQL and EDA, and developed fraud-detection workflows addressing severe class imbalance.

I am collaborative, adaptable, and effective in fast-paced, cross-functional settings, with experience coaching students in Python and data visualization and designing project-based AI learning for middle-school students. I aim to deliver data-driven insights that enhance operational efficiency and inform strategic decisions.
