ABOUT PATRICK OBRIEN
My background spans LAN, WAN, SD-WAN, routing, switching, firewalls, data centres, virtualisation, and hybrid cloud environments. I have led multi-year transformation programmes covering hundreds to thousands of sites, translating business objectives into standardised architectures, delivery roadmaps, and operational service models. This work has consistently focused on improving availability, reducing operational risk, and enabling future digital growth through simplification and automation.I am frequently engaged in complex or disrupted environments where infrastructure strategies require reset or redirection. Recent work includes joining the National Grid SCADA programme to redesign the network and infrastructure approach for critical national infrastructure, ensuring resilience, security, and operational continuity. I have also delivered major infrastructure transformations for organisations including Whitbread, Close Brothers Bank, and Transport for London, achieving measurable outcomes such as cost reduction, incident reduction, and improved service performance.Alongside technical leadership, I bring strong commercial and governance capability. I have managed significant infrastructure budgets, vendor and carrier relationships, and delivery partners, balancing cost control with long-term platform sustainability. My approach is grounded in established IT service management and programme delivery principles, ensuring technology investments are aligned with organisational priorities and risk tolerance.I hold a degree in Computing Science, an MBA, and Chartered IT Professional (CITP) status. My leadership style is collaborative and outcome-focused, with an emphasis on building high-trust technical teams, leading through ambiguity, and communicating complex technical issues clearly to senior stakeholders and executive audiences.
