Data Analyst at Electronic Arts · PhD, Experimental Psychology
I'm a Psychology PhD who blends behavioral science, product analytics, and machine learning to help teams make
data-driven decisions. I love digging into data to understand how people behave, turning insights into product
improvements, optimizing user journeys, and measuring the impact of AI and LLM tools.
I have hands-on experience building dashboards, running A/B tests, and developing predictive models to guide
product strategy. Skilled in SQL, Python, R, Power BI, and experimentation, I focus on driving real-world results -
from improving retention and forecasting outcomes to increasing conversion.
Led forecasting and analytics initiatives supporting portfolio risk management and strategic planning across thousands of businesses.
Automated KPI reporting and survey analytics, and built LLM-enabled workflow tools that improved operational efficiency, decision speed, and leadership visibility into performance.
