Executive Profile

Delivering complex technology change while keeping critical services stable.

I am a technology and programme leader with more than 28 years of experience across infrastructure, programme delivery, service management and cloud operations. I specialise in leading complex change for government and enterprise organisations, where reliability, compliance and clear accountability matter.

My experience covers the full delivery lifecycle, from bid and requirements through to migration, operations and continual improvement. I have led cross-functional teams of up to 251 people, built cloud service frameworks and catalogues for government customers, and established the governance, standards and automation that keep large-scale services consistent and compliant.

In December 2025 I rejoined NCS, where I lead the project team delivering the HTX xEDI project. Before that, as Vice President, Technology (Infrastructure) at Energy Market Company, I led the team supporting a 24x7 mission-critical environment, working with senior business leaders on budgets, technology roadmap, risk and governance. I am equally committed to developing people and to turning business priorities into practical technology outcomes.
