About Yann Elfersi

As a Data Scientist at Amazon, I lead the science effort for the Lead Management team, building statistical analyses and ML models to optimize targeting and forecasting for leads. With my strong foundation in modeling, research design, and data engineering, I have improved accuracy by 42% and established scalable data pipelines using AWS SageMaker, Lambda, and Step Functions. I have a Master of Science degree in Mathematics and Computer Science from CentraleSupélec, one of the most prestigious engineering schools in France. Prior to joining Amazon, I was a Technical Product Manager at NBCUniversal Media, where I collaborated with cross-functional teams to automate title matching operations, design and implement film box-office forecasting models, and monitor and facilitate project delivery. I am proficient in SQL, Python, and AWS, and I speak four languages: French, Hebrew, Spanish, and English.
