I build reliable data products and turn complex data into useful insights

Hi there, I'm
Juliette Wong.

I build and safeguard the data people rely on to make decisions, and every so often I turn it into something worth looking at.

About

I'm a data professional with a background spanning software engineering, analytics, and data quality. I'm currently a Data Quality Analyst at OptionMetrics, where I work on the reliability and accuracy of financial data products. Previously, I spent four years at Mastercard building and improving self-service analytics products used by clients to understand portfolio performance.

Alongside my professional work, I'm completing a Master of Science in Analytics at Georgia Tech, building on my undergraduate background in Mathematical Sciences from Carnegie Mellon University. I'm particularly interested in the intersection of data, technology, and problem-solving.

Outside of work, I enjoy dancing, exploring New York's food scene, volunteering, listening to K-R&B (JUNNY is on repeat), and watching the Mets (though maybe not in 2026).
