Who am I and what do I do?

I am a well established, energetic and highly motivated consultant, with extensive experience in the design, security, delivery and management of all scales of infrastructure, across varied business sectors. I enjoy successfully delivering challenging, complex projects involving cutting edge technologies that enable organisations to access fast and effective business gains.

I have extensive experience in a wide range of transformational technical solutions that are aligned with business goals and needs, managing virtual teams and resources through the full lifecycle to successful delivery. I enjoy working with a wide range of stakeholders within and outside of the IS arena and see knowledge sharing as a key component to all my roles.

I relish the opportunity to explain complex technical issues to audiences at all levels, including CxO and board level, and can draw on my extensive experience in this area to promote understanding and develop shared, high level technology roadmaps, designed to deliver real business value. I have proven abilities in security consulting, infrastructure architecture and design, rapid prototyping of business ideas, mentoring and passing on knowledge to direct reports and senior staff, as well as developing and implementing transformational infrastructure at an architecture and delivery level.

I have developed IaaS and PaaS infrastructure roadmaps for multiple clients to enable migration to various private/hybrid Cloud models. These projects were aligned with business-driven organisational transformation, to enable greater flexibility, faster time to market, and improved customer interaction.
