IT Transformation & Portfolio Leadership
Turning complex enterprise IT transformations into controlled, measurable business outcomes.
Led IT Transition & Transformation (T&T) programs and portfolios across global, multi-region environments, from bid/RFP and discovery through planning, delivery, stabilization and operational handover. Delivered across applications, infrastructure, networks, cloud, ERP, identity and cybersecurity workstreams, integrating technical delivery, business objectives and security requirements within a unified program structure.
Established delivery governance, reporting and decision-making structures across international, cross-functional and multi-vendor teams. Established KPI and milestone reporting, RAID management, and SteerCo and CAB governance, with clear ownership of dependencies and risks and defined escalation paths. Identified delivery constraints early and resolved them across technical and organisational boundaries before they became program-level issues.
Provided CAB and Change Management consultancy with a strong Cybersecurity Governance and GRC focus. As a Security Lead, reviewed Change Requests, solution designs, security and compliance risks, and proposed implementation approaches against the architecture, operational objectives and end-to-end dependencies of the enterprise environment. Provided expert recommendations on the most secure and operationally viable implementation approach, balancing cybersecurity, regulatory compliance, technical feasibility, business requirements and service continuity.
Applied waterfall, Agile and hybrid delivery models within the organisation’s governance, SDLC and operating model, adapting delivery cadence and controls to the operating environment rather than imposing a methodology. Aligned architecture, application, infrastructure, network, cybersecurity and operations teams, vendors and business stakeholders throughout delivery, with ITIL service management and security governance embedded through operational readiness.
Led and supported transformation decisions across scope, architecture, cost, risk, security, resourcing and supplier management, with executive reporting based on delivery status, KPIs, dependencies and business impact. Transitioned programs into BAU with operational ownership, documentation, controls and governance in place — leaving sustainable solutions and delivery structures beyond program closure.
PMP-certified and CISM-qualified, combining program and portfolio leadership with hands-on governance and technical depth across Azure, AWS, SAP S/4HANA, enterprise infrastructure, IAM/PAM, Zero Trust, cybersecurity risk and digital operational resilience.
