Reverse ETL is the process of moving data from a central data warehouse back to operational systems (CRM, email platforms, analytics tools, databases). Traditional ETL pulls data into warehouses; Reverse ETL activates insights by sending processed data back out. A typical example: sync customer segments computed in the warehouse back to Salesforce, so sales reps see them in real-time. Reverse ETL combines data engineering (pipeline design), SQL/analytics (data transformations), and API integration (pushing to external systems).
