Business Intelligence Engineer @ Amazon
About
I am a Data Scientist and Data Engineer who thrives at the intersection of machine learning, big data, and cloud platforms to solve high impact business problems. With a Master’s in Applied Data Science from Syracuse University and experience at Sam’s Club and Modak Analytics, I combine strong technical execution with strategic thinking. My expertise includes predictive modeling, churn analytics, deep learning, and building scalable data pipelines across AWS, Azure, and GCP. At Sam’s Club, I uncovered a significant churn trend connected to credit card cancellations, which informed the design of a targeted retention strategy that improved renewal outcomes. At Modak, I automated more than 150+ clinical trial ETL pipelines, reducing insight delivery time by two weeks and improving system reliability by thirty percent. I am passionate about using AI to create measurable value, whether through interactive dashboards, NLP applications, or real time anomaly detection systems. I welcome connections with those building data driven products or scaling applied AI initiatives.
