HP accredited platform specialist, engineer No. 0044044098.
An energetic, practical and organised IT professional who has worked within the dynamic and
demanding financial sector for +15 years, most recently as data centre manager / coordinator for
a leading clearing house that serves major global exchanges and platforms.
Rolled out a new data Centre solution in France in 2012/3 and relocated a live data centre in
London to another site through the second half of 2014, meeting deadlines and budget forecast
for both regulatory-driven initiatives.
Confidently working side by side various business departments to regulalrly deploy new projects
within the data centre on time, whilst avoiding risk to the Production estate.
Has proven team and self management skills and enjoys planning and implementing practical,
considered solutions with a strong delivery focus and has regularly demonstrated the ability to
take on and own new responsibilities in an aggressive and dynamic environment, working within
an ITIL framework and completing tasks with integrity, working to a risk-avoidance methodlology
while retainging the flexibility to deliver the dynamic business requirements as well as the ongoing
maintenance via Platform Support teams.
Responsible for review and approval of Change tickets for all activities in the company’s data
centres.
Working with local and offshore support teams and engaging multiple front office and back office
teams to deliver a consistent, high-quality service.
I have proactively initiated and coordinated with Platform teams to assist in the virtualisation of
old/underused servers to more quickly regain space and power required for new projects and to
be able to consolidate the existing estate to identify available footprint space and avoid expensive
footprint expansion costs.
I have also been able to offer and exercise a hardware break-fix service above the current vendor
agreements, from fault diagnosis and component replacement to memory upgrades on HP, SUN
and UCS kit, when required, meaning that time is saved in admin and service outages, being able
to attend site, where available, at short notice, and there has been a saving of cost where non-
warranty works would have incurred charges. I believe cost/benefit planning is a major part of the
role to be able to show a value to the customer (the business).
I enjoy being part of an operation that has the power to shape its own success, giving maximum
benefit to its customers in both efficiency and performance as well as promoting a healthy work
environment that people enjoy being part of.
