What I'm looking for

I am looking for opportunities that foster innovation and collaboration, where I can leverage my data science expertise to drive impactful business decisions.

I am a Principal Data Scientist with over a decade of experience leveraging data insights to drive strategic business decisions. My proficiency in advanced analytics tools enables me to effectively detect and prevent fraud in credit and debit transactions. I have a deep understanding of statistical learning and data visualization, consistently delivering innovative solutions to complex problems.

Currently, I work at Discover Financial Services, where I develop and implement fraud decline rules using advanced analytics and machine learning. My efforts have significantly improved customer experience while balancing risk mitigation. I have also spearheaded cross-functional initiatives to proactively address evolving fraud landscapes, collaborating with various teams to enhance our strategies and outcomes.

Previously, as a Senior Data Analyst at Sears Holding Corporation, I built and automated offer recommendation models that drove a 3% margin lift. My experience includes pioneering new data visualization techniques and utilizing machine learning methods to provide strategic recommendations. I am passionate about transforming raw data into compelling narratives that drive business success.
