I’m an Economics graduate and CFA candidate with a strong focus on financial modeling, business analysis, and data-driven decision making. I enjoy turning complex data into clear, actionable insights through reporting and trend analysis.

In my current role as a Data Analyst at Next Innovation LLC, I analyze offensive strategy patterns using play-by-play data to compare structured set plays versus random possessions. I also perform model selection to identify the best GLM framework for predicting player development outcomes and support my recommendations with statistical reasoning.

Previously, as an Internship of Business Analysis at Microsoft, I analyzed Azure operational and subscription data with SQL and Excel to investigate discrepancies between membership growth and monthly revenue across subscription tiers and billing status. I gathered and organized public financial data and market research for product areas including Azure, Microsoft 365, and Xbox, and helped prepare data-driven PowerPoint presentations with clear visualizations.

My experience also includes a Product Analyst Intern role at Jiangsu Huaxi Securities Co., LTD., where I supported client advisory work by researching market trends and assisting in the preparation of tailored investment suggestions based on risk profiles. In projects, I’ve built analytical tools and forecasting models using VBA/Excel and performed policy impact research in Stata with OLS and fixed-effects regression.
