• Design, build, and analyze large, complex data sets from structured and unstructured sources, including data lakes, databases, cloud platforms, and enterprise data environments, while ensuring data quality, integrity, and usability.
• Use simulation techniques and statistical analysis to identify key drivers of customer survival, interpret model outputs, and deliver clear, actionable recommendations to business stakeholders.
• Develop scalable coding solutions using Python and PySpark/Spark, with proficiency in modern machine learning libraries and frameworks to support robust model development and production-ready implementation.
• Work across big data platforms such as Databricks and Snowflake to support data processing, model development, experimentation, and deployment in large-scale analytics environments.
• Partner closely with cross-functional teams to communicate findings, align analytical solutions with business objectives, and support enterprise innovation through advanced analytics and machine learning.
