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. ⸻ Key Accomplishments • Fraud Prevention in Crypto: Designed and implemented fraud detection models for PayPal’s crypto division, enhancing real-time monitoring and reducing false positives across digital asset transactions. • Debit Card Risk Optimization: Supported fraud prevention and performance analytics for PayPal’s debit card products, streamlining investigation processes and improving customer security. • Risk Modeling in Banking: As Senior Risk Analyst at G&T Continental Bank, developed predictive models and risk dashboards that improved portfolio monitoring and informed credit policy decisions. • Data Visualization Excellence: Built and deployed high-impact dashboards using Power BI and Tableau, improving cross-team visibility into risk metrics and business performance. • Cross-Functional Collaboration: Successfully partnered with product, compliance, and engineering teams to operationalize analytics and implement risk solutions at scale.
