Experienced IT Professional

United Kingdom - Tests: 2 - Portfolio: 1

I have been working in various IT departments over the last 17 years. I'm originally from the UK, now living in the USA. I am able to work within Pacific, Eastern & GMT business hours. Most of my career has been working for international investment banks. I started in 3rd line support before creating & heading up a team responsible for rapid deployment strategy management. The process we designed was taken as the sole methodology for the bank's work area recovery & replaced the production build processes. More recently, I worked in Business Continuity Management & Disaster recovery for a large Spanish bank where I was solely responsible for the design, implementation & support for their emergency relocation planning. This involved performing all levels of technical support to the business users & managing the expectations of their Executive Directors, as well as designing, testing & developing an automated environment would meet all of their critical process needs. I am able to write code in VBA, VBS and create applications in VB.net, including GUI front ends for an SQL backend and/or Active Directory interaction.
