_About
As Head of Business Advisory at Restack, I established and scaled a full-service capability delivering IT strategy, enterprise architecture, and fractional CTO/CIO services across South Africa and globally.
My work spans strategic engagements with South Africa's largest financial institutions, including architecting platforms managing assets equivalent to 25% of the nation's GDP and redesigning enterprise IT operating models for major retirement fund administrators.
I specialize in translating complex business challenges into actionable technology strategies, with deep expertise in multi-cloud architectures (Azure, AWS, ALP), enterprise capability design, and governance frameworks.
My approach combines strategic vision with hands-on technical depth, ensuring alignment from board-level strategy through to implementation.
