What I'm looking for

I am looking for a collaborative environment that values data-driven decision-making and offers opportunities for professional growth.

I am a dedicated data analyst with a strong background in data visualization and predictive modeling. Currently, I work as an Administrative Analyst at the San Francisco Unified School District, where I wrangle, analyze, and visualize data to support decision-making processes. My role involves building interactive dashboards that help school leaders and researchers track progress and identify areas for improvement.

Previously, I interned at DataGlacier, where I utilized Python and R to prepare visual reports and predictive models, aiding clients in making informed investment decisions. My experience as a Research Assistant at the Brain Game Center further honed my skills in maintaining data pipelines and documenting research methodologies. I am passionate about leveraging data to drive impactful decisions and improve operational efficiency.
