Mar 2018 - Present

Senior Manager Network Operations

Newark, New Jersey, Us

(Contractor) Prudential - Head of Network Operations – October 2016 to March 2018 Responsible for 16 Network engineers and 2 team leaders and reporting into the Global Head of Network Services During my time so far at Prudential (PGDS) I have undertaken improvement to service and automation. Previously code was deployed direct onto production systems with no prior testing which lead to a number of incidents caused by change. I researched solutions of onsite testing and offsite test. The decision was to deliver the offsite test being the most cost effective and flexible model. So I introduced a new test environment so that code and configurations can be upgraded on non production environment, due to the size of the team we have a third party vendor who hosts this environment off site and provides us engineer resource to conduct the full testing. I have successfully introduced automation using Solarwinds NCM to deploy scripted configurations/Operation System upgrades across 700 devices.I have created a number of Terms of References, from automation, Network monitoring improvements, Network Security reviews and Documentation. All of which are currently in flight and many improvements have already been put in place. The priority of focus is on operations and service availability. Due to a lack of focus on incidents I introduced an agile approach utilizing huddles to give focus to incidents in the very busy incident, change, task & project environment. Since joining, service to the business has vastly improved by providing more stringent change process within the network area, utilizing the test environment to test code prior to implementation and testing major configuration changes.
