Dataform ecosystem with Slack alert integration

cloud slack

I assisted in the migration from BigQuery to Dataform to enhance control and flexibility over data tables. My contributions included creating validations, tables, SCD2 functions, and reusable functions that streamline project-wide updates by modifying only the function itself. Additionally, I implemented assertions, tags, and other features to improve data governance and workflow efficiency. I also supported the integration with Slack to enable real-time alerts for table assertions and validations, ensuring proactive monitoring and issue resolution.
