job
senior member of the strong Infrastructure team
unknown.
Exchange Migration: from 2003 to 2010: during the year 2011, I spearheaded the project when a cross office Exchange migration took place. During this time, I managed migration from locally hosted mail security gateway to cloud based (proofpoint) email firewall. I have also configured exchange archiving using Symantec Ent vault and later Global Relay.
In addition, I have implemented and maintained several technologies in Investcorp's London office as well as remote offices in Middle East and New York. As a senior member of the strong Infrastructure team of Investcorp, I've maintained the Windows based core systems and a number of other integrated services including Exchange. I have worked with cutting edge technologies such as Cisco FlexPod, Checkpoint R77, Websense Triton, Proofpoint Enterprise security and many more. We have integrated PowerShell scripts with various scheduled tasks and saved time for repetitive tasks. We have developed PS commands to run during BCP scenarios to fail over systems to remote sites and start stop replication and similar admin tasks.
During my last year with Investcorp, a technology transformation initiative required me to explore and work with several state-of-the-art technologies. From traditional client server technology Investcorp moved to Cisco FlexPod and Software defined networking co-located in distant datacentres with full server and desktop virtualization. During this transformation I have expanded my skills and experience to Data Centre related technologies including SDDC (Software defined data centre). The transformation involved working out of Investcorp's New York as well as Middle East offices.
November 2008 to February 2009
Made redundant from First Union in October 2008 due to the worldwide financial crisis of 2008. During this gap time I trained and upgraded my technology skillset.
