Define and differentiate source-aligned, domain-aligned, and consumer-aligned data products.
Collaborate with business analysts, architects, data engineers, and other stakeholders to operationalize data models through ingestion, transformation, and curation pipelines.
Support data governance initiatives including metadata management, data quality, lineage, documentation, and access management.
