About

I’m a UC San Diego graduate with a B.S. in Cognitive Science: Design and Interaction and a growing focus on data analytics. My background combines technical problem-solving, data visualization, and an understanding of how people interpret and use information.

I use Python, SQL, Tableau, and Excel to analyze structured data, identify patterns, build visualizations, and improve reporting. My experience coordinating operations for 60+ employees and managing financial reporting for a $5,000 annual budget strengthened my skills in data accuracy, documentation, workflow tracking, and process improvement.
