The business challenge

The client's reporting supported large-scale operational initiatives across Tableau, SAP BusinessObjects, Power BI, Salesforce, Snowflake, SQL and Alteryx. The challenge: modernize reporting across all of these platforms without losing existing business logic or data integrity.

The solution

As Technical Project Manager, Susan Zielinski coordinated eight data engineers and analysts — requirements, priorities, QA, delivery schedules and stakeholder communication — while leading the technical migration of Tableau and SAP BusinessObjects reporting into Power BI, with reconciliation against the legacy environment.

Implementation

How the system was built, step by step.

1

Migration with validation

Existing business logic reviewed and recreated in semantic models, DAX, Power Query and SQL — with reconciliation against the legacy environment.

2

Data integration

Salesforce, Snowflake and SQL unified through Alteryx ETL, APIs, Power Automate, RPA and Power BI gateways; Azure CI/CD for controlled deployment.

3

Governance & QA

Quality assurance extended to machine-learning models supporting risk assessment and procurement forecasting.

Business results
