Into Narratives

I'm an MIS student at the University of North Carolina at Charlotte with a passion for uncovering the stories hidden in data. From building predictive models that project six-figure retention value to driving million-dollar sales through performance analytics, I thrive at the intersection of business and technology.

My toolkit spans SQL, Python, SAS, Tableau, and BigQuery — but what sets me apart is translating technical findings into actionable business strategy. Whether it's a churn prediction model or a logistic regression campaign optimizer, I focus on the "so what?" that moves the needle.
