What I Do

I specialise in bridging the gap between technology and business. Whether you’re looking for strategic advice, need a seasoned expert as a part-time CTO or CISO, or want an engaging speaker for your next event, I’m here to help.

Here’s how I can support you:

  • Strategic Advice: Helping leaders and boards make confident decisions about IT, cybersecurity, and digital transformation.
  • Fractional Roles: Offering my expertise as a part-time CTO or CISO to drive innovation and security without long-term commitments.
  • Speaking & Workshops: Sharing insights and practical advice at events, conferences, or tailored sessions.
  • Personal cyber hygiene and protection: help you and your family to ensure your digital lives are safe and secure.

A Bit About Me

I have extensive knowledge and experience in cybersecurity, information technology, and digital transformation. I use my expertise to ensure that businesses closely align their technology stack with their business strategies. My colleagues, clients, and senior executives, such as CIOs and CTOs, acknowledge my technical and business acumen in advancing cybersecurity within their diverse business supporting technologies, including IT, cloud, data, and server architectures.

I’ve worked with some of the world’s most respected organisations, from government bodies to global tech companies. I love tackling challenges, bringing fresh perspectives, and ensuring technology works for people—not the other way around.

When I’m not immersed in tech and strategy, you’ll likely find me sharing ideas with brilliant minds, mentoring future leaders, or enjoying quality time with my family.
