Technology Executive | Strategy | Transformation | Cybersecurity | AI & Digital Enablement
I am a technology leader with 20+ years of experience progressing from hands-on engineering and infrastructure roles through IT management to enterprise technology and security leadership.
My background spans technology strategy, cybersecurity, infrastructure modernisation, digital transformation, AI governance, operational resilience, IT/OT, vendor management and business partnering.
I am particularly interested in the point where technology stops being a support function and starts becoming a practical business enabler.
- Technology strategy and transformation
- Cybersecurity, risk and resilience
- AI governance and responsible adoption
- IT operating models and business partnering
- Infrastructure and platform modernisation
- Secure delivery and operational readiness
- Data governance and secure information handling
- Vendor, commercial and technology investment decisions
- IT/OT and enterprise systems
- Practical automation and technical controls
A focused practical toolkit connecting data classification, lineage and governance decision rights.

Practical, anonymised technology leadership playbooks covering transformation, M&A, architecture, integration, resilience, operating models and delivery governance.
Technology Leadership Playbooks
Practical leadership and transformation case studies across cybersecurity, AI adoption, business partnering, digital transformation, IT/OT and secure environments.
Security governance, control architecture, resilience and practical alignment across ISO 27001, Essential Eight, NIST CSF, SOC 2, PSPF and APRA CPS 230/234.
Practical AI governance, risk assessment, acceptable use, Shadow AI controls, adoption and implementation patterns.
Technology operating models, service management, governance, business-led prioritisation, executive metrics and technology investment practices.
Practical technical knowledge, automation and control patterns across identity, Microsoft 365, secure delivery, resilience, infrastructure and security.
The repository includes implementation examples, reusable control patterns and a playground for experiments and learning.
I am not a full-time software developer.
The technical material here reflects a technology leadership approach that stays close enough to engineering, infrastructure and security to understand how controls actually work.
The library connects:
Business Problem → Practical Pattern → Technical Control → Evidence → Outcome
Current areas include:
- Identity and access management
- Microsoft 365 and Microsoft Graph
- Secure delivery and SDLC
- Incident response and disaster recovery
- Infrastructure operations
- Linux and cloud operations
- Network and IT/OT controls
- API and integration governance
- Data lifecycle and secure exchange
- Monitoring and observability
- Endpoint lifecycle
- Secrets and certificate management
- Technical debt and end-of-life management
The objective is not to build a collection of scripts for its own sake.
A stronger pattern is:
Policy says what must happen.
A technical control makes the expected action repeatable.
Evidence shows that it happened.
My approach to AI adoption is:
Governance → Pilot → Adoption → Measurement → Scale
The emphasis is on practical use cases, appropriate data controls, user enablement and evidence of value rather than simply deploying licences.
The supporting material covers:
- AI use-case assessment
- privacy and data classification
- acceptable use
- DLP and Shadow AI
- human review
- adoption telemetry
- risk and control decisions
- scaling decisions
My security approach is risk-led and proportionate.
The objective is not to implement more security for the sake of it.
It is to understand:
Risk → Business Impact → Appropriate Control → Evidence → Improvement
Areas represented across the repositories include:
- ISO/IEC 27001
- Essential Eight
- NIST Cybersecurity Framework
- SOC 2
- APRA CPS 230 / CPS 234
- third-party risk
- incident response
- disaster recovery
- security metrics
- identity and access governance
- secure environments
Technology leadership works best when the business owns priorities and trade-offs while technology owns execution quality, dependencies, risk and technical integrity.
A useful progression is:
Reliable Service → Trust → Business Partnership → Strategic Influence
The repositories intentionally connect executive technology leadership with enough technical depth to show how the underlying systems and controls operate.
I also keep a small playground within the Technology Automation repository for experiments, language refreshers and technical learning.
That content is deliberately separated from the more formal control modules.

Technology leadership requires both strategic perspective and enough technical understanding to challenge assumptions, ask better questions and make practical decisions.
That is the purpose of the work collected here.
