## Career journey
- Technical foundations (Built in practice): Deep, hands-on technical expertise: engineering, platforms, networks and the systems behind critical services. Building, fixing and supporting technology created the judgement to question a design, understand a failure and respect the effort behind delivery.
- National leadership (Taking responsibility for service): From solving problems to leading the national functions that keep a business running. Reliability, workforce capability, suppliers and operating ownership had to work together for the people and customers depending on them.
- Asia Pacific leadership (Leading across difference): Regional responsibility across cultures, languages and time zones, inside global media and medical-technology leaders. Effective leadership meant listening to local teams and finding a shared direction without treating every market as the same.
- Global enterprise (Connecting the wider enterprise): Multi-billion-dollar international groups: shared platforms, cross-border information, global providers, acquisitions and valuable intellectual property, where a change in one business could affect services and risk everywhere else.
- CIO & CTO · Big 4 (Carrying the executive mandate): Successive CIO, Director of Technology Operations and CTO appointments inside a Big 4 firm, leading national and APAC teams through cloud, digital platforms, workforce transformation and a global business separation. Recognised in Australia’s CIO50.
- Company Director · Big 4 (Company-level accountability): Three years as a Company Director of the Big 4 services entity supporting 10,000 people: governance, commercial commitments, technology and cyber risk, and workforce continuity through COVID.
- Previously: Big 4 multi-billion-dollar professional services and consulting · Australia’s largest not-for-profit health insurer · global media and medical-technology leaders.
