    Demonstrable skills and experience in both Enterprise and SME (MSP Clients) Project and Programme Management, based on the principles and methodologies of industry standards such as PRINCE 2 and PMP. With further demonstrable experience of managing teams in excess of 30 members including local hire and remote resources, together with all aspects of annual performance appraisals, and contractor negotiation, with an excellent understanding of the latest ITIL methodologies for ITSM.

I have a strong mix of corporate enterprise, SME and entrepreneurial experience, and to expand on that, my experience has afforded me the ability to learn the complex matrix management structures and business models which predominantly gained within Global Financial Services Industries (Investment Banking and Global, Corporate and Specialty Insurance). Where conversely some of my most recent and earlier career experience was based in one of the most competitive customer service industries, and to achieve success in this, I had to be flexible to market conditions, so that I could maintain strategic focus so as to continually meet my financial targets.
