Data Warehouse Migration

DWH project migration from Talend to dbt with ongoing maintenance and optimization.

Migrated an existing enterprise data warehouse built on Talend to a modern dbt (data build tool) stack, significantly improving maintainability, testability, and documentation coverage. The migration involved rewriting hundreds of Talend jobs as dbt models, adding data quality tests, and setting up a CI/CD pipeline for model deployment. Post-migration, ongoing maintenance included performance tuning, incremental model optimization, and expanding test coverage. The new stack reduced transformation run times and made the codebase accessible to a broader team.
