What I'm looking for

I'm looking for an analytics-focused role where I can apply financial, product, and market research to practical decisions, deepen my technical skills, and contribute to data-driven teams.

I've supported investment management at Oriza Seed Investment Management, where I managed quarterly private equity fund reporting, analyzed portfolio performance, and improved PMS data integrity across 35 portfolio companies to 98%.

At iFLYTEK Technology, I tested and improved the Alpha Egg AI Go teaching product through user simulation, interviews, issue tracking, and product requirement development. My work helped drive 20 targeted improvements, with 85% implemented in official releases, while resolving 60+ technical defects with research and development teams.

I've also conducted commercial due diligence for 12 IPO targets at Soochow Securities, using Wind to assess corporate structures and financial performance. My research spans new-energy materials, advanced manufacturing, consumer behavior, and portfolio selection using machine learning.

I'm pursuing an MS in Business Analytics at USC Marshall and bring hands-on experience with Python, R, SQL, Power BI, Tableau, and financial datasets. I enjoy translating complex analysis into practical product, investment, and business decisions.
