What I'm looking for

I am looking for a role that allows me to leverage data analytics to drive strategic decisions and improve business outcomes, ideally in a collaborative and innovative environment.

I am a dedicated data analyst with a strong background in leveraging data to drive business decisions and enhance operational efficiency. My experience spans various industries, where I have successfully built and maintained automated dashboards, developed SQL-based data models, and provided actionable insights that have significantly influenced product strategies and customer satisfaction.

At Medallion, I currently focus on creating automated dashboards that help customers track business performance. Previously, at TeePublic, I analyzed supply chain data, leading to a 20% increase in operational efficiency. My role at Betterment as a Senior Data Analyst allowed me to deliver insights on investment products totaling over $5 billion in assets under management, directly impacting strategic initiatives across multiple teams.

With a B.S. in Applied Mathematics from CUNY City College of New York, I possess a solid analytical foundation. I am passionate about using data to uncover trends and drive decision-making, and I thrive in collaborative environments where I can work with cross-functional teams to define data requirements and solutions.
