Senior Network Engineer at International Game Technology

• United Kingdom - Birmingham
• My current job since January 2010

Reduced the operating costs of EGM “Electronic Gaming Machines” by 20%, reduction in costs are achieved by eradicating, consolidating and migrating existing network infrastructure across several sites to cloud based service offering from few geographically dispersed data centres.

A further reduction in costs are achieved by using squeezing / compressing WAN bandwidth by utilizing a combination of Riverbed and open source technologies which in return increases the capacity of existing bearer up to 30x, thus eliminating the need to upgrade costly bandwidth. IGT has witnessed 300 Mbps through over a 30 Mbps bearer.

Conceptually envisioned, designed, implemented and now successfully operating inter-continental core network consisting Cisco Nexsus, ASR9K, ASR 1000, Cisco Metro 3600, 6500, 3750, Juniper, Riverbed, Checkpoint, Sonicwall and open source unix / linux based technologies.
