I am a results-driven Data Scientist and Senior Analyst with a strong foundation in financial services, fintech, and crypto. My career spans roles in fraud prevention, risk modeling, behavioral analytics, and performance reporting—with hands-on experience in both traditional banking and emerging digital finance. I have held impactful roles at leading organizations including PayPal, where I’ve contributed to key fraud prevention strategies for both debit card products and crypto assets, and G&T Continental Bank, where I served as a Senior Risk Analyst in the Consumer Risk Department.
With deep technical expertise in Python, SQL, BigQuery, RStudio, Power BI, and Tableau, I specialize in transforming complex data into actionable insights that support risk mitigation, strategic decision-making, and business growth. My work consistently bridges technical analytics with real-world operational impact.
