About
I’m a Marketing student at the University of Illinois Chicago with a concentration in Data-Driven Marketing and a minor in Business Analytics. I enjoy transforming data into clear, actionable insights through visualization, statistical analysis, and marketing research, using tools like IBM Cognos, R, SQL, Excel, and WordPress.
This portfolio showcases projects that combine analytics, AI, and business strategy to solve real-world marketing problems. I believe the best decisions come from pairing data with critical thinking, and I’m committed to using AI responsibly to create transparent, evidence-based solutions that drive meaningful results.
