What I'm looking for

I’m pursuing VP-level enterprise technology and data leadership roles where I can own strategy, scale global operating models, lead AI-led transformation, and deliver measurable value through data governance, cloud modernization, risk management, and disciplined execution.

At Unilever, I lead global master data strategy, governance, and multi-country delivery across an 8+ country footprint and a 50+ person internal and partner organization. I direct SAP MDG modernization, data readiness, vendor ecosystems, and AI-enabled data quality initiatives that improved data quality by 30%, reduced incidents by 40%, and achieved 95%+ adoption across business units.

Across 20+ years with Unilever, General Electric, Accenture, and Cognizant, I’ve translated enterprise strategy into scalable operating models spanning data platforms, cloud modernization, identity and access, cybersecurity, and automation. I bring P&L stewardship, executive stakeholder alignment, and global delivery leadership to VP-level technology and data roles focused on measurable business value.
