Collaborate with application, integration, and reporting teams to ensure reliable and efficient data pipelines. Support legacy data migration, ensuring data accuracy, completeness, and reconciliation during system transitions. Implement error handling, logging, and monitoring for all ETL and data movement processes.

Collaboration & Documentation

Work closely with application developers, architects, QA teams, and business stakeholders to translate requirements into robust data solutions.
