Model data for analytics use cases (e.g. star schema for BI, curated datasets for data science).
Ingest, transform & govern data
Ingest data from APIs, files, databases and SaaS sources into data lakes and lakehouses.
Implement clear and testable transformation logic (data quality checks, deduplication, SCD, CDC, business rules).
Apply data governance best practices (cataloguing, lineage, RBAC, masking of sensitive data).
Operate & optimize
Set up CI/CD and deployment pipelines (Azure DevOps / GitHub) for Databricks assets (notebooks, jobs, pipelines, workflows).
Using Terraform to automated IaaC setup and reusability
