• Help standardize common source data fields such as entity identifiers, transaction or event IDs, timestamps, event types, measurement units, and geography fields.
• Support data transformation work required to prepare daily summary, event-summary, exposure, behavioral, and contextual feature datasets.
• Document source tables, transformations, assumptions, data quality findings, known limitations, and operational procedures for actuarial users.
