Summary

I have over 5 years working in the networking industry. Initially starting at Parseq as a Network Engineer and was responsible for various aspects of the network, ranging from switches/routers to firewalls. Parseq’s network was heterogeneous, allowing myself the exposure to various platforms and technologies. I have also spent a 1.5 years at Capita Updata Infrastructure, initially joining for the Wales PSBA project. My prime responsibility was to migrate the DSLAMs and CPEs onto Updata’s monitoring platforms and standardising the configurations to meet the expectations of the organiation. I was then assigned to Norfolk City Council’s project, which primarily involving Cisco products, upgrading the already existing equipment and migrating the newly installed CPEs onto the new circuit. My most recent role was based at Sky, where I was the focus point for integrating networks within the EMEA WAN for long term SkyQ project.

• Sky - Network Security Engineer – February 2017 - August 2018 (Contract) Initially joined Sky to be a part of the support team, which spanned for 2 months. The role was vast and included troubleshooting various issues reported by engineers and developers from diverse backgrounds. The issues reported could range from firewall blockages to routing/switch related issues. The role proved to be excellent in gaining all round experience in a number of aspects, ranging from load balancers, routing/ switching and Firewalls.

I was moved onto the projects department after spending 2 months in support, which was very useful as it provided more insight and allowed myself to familiarize with the network environment. The projects role is different to the support role, as I solely focused on delivering and implementing changes to the time frames provided. The projects I am responsible for are:

• Sky EMEA WAN Integration for SkyQ

The project was demanding as there were a number of deadlines that I had to meet before launching services and applications for SkyQ. The role mainly involves implementing firewall changes and advertising routes that weren’t present in the EMEA WAN routing table, thus allowing end to end reachability.

• Cisco G1 Refresh project

The project was based on migrating from hardware based servers to virtual images. As a result of such migration, a number of firewall changes had to be implemented, allowing the new addresses to the required destinations. Equipment:
