Financial Services — Data Engineering
Case Study
Challenge
A regional bank's regulatory reporting relied on nightly batch jobs across a fragmented mainframe and on-prem SQL Server estate, with reporting lag that put compliance deadlines at risk.
Solution
Migrated core reporting pipelines to a governed Snowflake lakehouse orchestrated by Airflow and dbt, with CDC ingestion from the mainframe replacing nightly batch extracts.
Architecture
- CDC ingestion layer for mainframe and SQL Server sources
- dbt-managed transformation layer with automated testing
- Snowflake as the governed single source of truth
- Power BI semantic layer for regulatory and executive reporting
