I'm pursuing Data Science at the University of North Texas and use data analysis to identify trends, support decision-making, and improve business outcomes.

In a social media sentiment analysis project, I cleaned and processed Twitter (X), Facebook, and Reddit data using Python and NLTK. I classified posts by sentiment, visualized public-opinion trends, and evaluated the model at 76.69% accuracy.

I've also analyzed job applicant demographics with Python, R, and Tableau, using exploratory analysis and statistical testing to examine gender and ethnicity patterns across roles.

For a bookstore database project, I collaborated on a MySQL system for inventory, sales, customer, supplier, and order-tracking data. My academic work is supported by a 3.8 GPA and recognition on the UNT President's List.
