Turning data into decisions

Python, SQL, and data visualization — with an eye for the story in the numbers.

About me

I'm a recent Computer Science graduate from San Diego State University with a passion for uncovering stories hidden in data.

I earned my B.S. in Computer Science, Magna Cum Laude (3.75 GPA), in May 2026, and I'm now pursuing my M.S. in Big Data Analytics at SDSU. I work in Python for data manipulation, SQL for database querying, and Tableau for visualization — my approach is methodical, and I believe the best insights come from asking the right questions and letting the data tell its story.

Growing up in San Diego, I've been shaped by this city's diversity and its unique challenges in healthcare access. My work at an independent pharmacy showed me how data-driven solutions can improve people's lives — identifying cost-saving opportunities in prescription patterns, streamlining processes that directly impact patient care. That experience is what pulled me toward data in the first place: seeing how the right numbers, presented the right way, change what people decide to do next.
