- Conduct data validation, reconciliation, and quality checks to ensure data accuracy, completeness, consistency, and integrity.
- Execute data migration activities from legacy databases or existing data platforms to Snowflake, ensuring minimal data loss and business disruption.
- Optimize SQL queries, warehouse configurations, and data processing workflows to improve performance and manage compute costs.
- Design and implement data models, schemas, fact tables, dimension tables, and other warehouse objects to support reporting and analytics.
- Apply Data Vault 2.0 modelling concepts, including Hubs, Links, and Satellites, where applicable.
- Collaborate with data engineers, business analysts, BI developers, and stakeholders to understand requirements and deliver reliable data solutions.
- Support integration with Azure Data Factory (ADF) and Databricks for data ingestion, transformation, and processing.
- Troubleshoot data pipeline failures, data discrepancies, performance issues, and production incidents.
