  • Create data models and automate workflow orchestration with Airflow, dbt, Databricks Workflows, Azure Data Factory, or comparable tools.
  • Use event-driven and streaming patterns while establishing governance, lineage, quality controls, access management, and observability.
  • Track data freshness, pipeline resilience, SLA performance, scalability, efficiency, and operating costs.
