At BHP, I lead functional design and delivery of HR and payroll technology solutions integrated with SAP and ServiceNow. I define requirements and functional specifications, and work with HR, Payroll, development, QA, and change management teams through testing and post-go-live validation.

At AB InBev, I delivered Workday implementations across Core HCM, Compensation, and Recruiting, and led the Oracle-to-Workday data migration using EIB and Workday Studio. I also managed payroll and benefits integrations and developed Workday and Power BI reporting; earlier, I supported HR systems, analytics, and payroll operations at Syneos Health Clinical Solutions, S&P Global, and Givaudan.
