o Datacenter migration project

o New building network and security design and configuration. Included Datacenter switch N9K, N3K, N7K, Access Switch Cisco 29xx series, WLC, 250 AP, Firewall, Cisco ISE 11/2014 - 11/2015 - Senior Network Datacom Engineer - HUAWEI (TURKEY) Rollout and swap projects for vendor clients; Turkcell, Turkish Telekom, Superonline. Planning and implementing swap (mostly from Cisco and Alcatel) and rollout projects. Configuring, troubleshooting and optimizing provider scale routing and switching infrastructure

o Implemented services such as L2VPN, L3VPN, Internet, Voice circuits of provider’s corporate subscribers. o Implemented new PE (provider edge) and P (provider) routers to extend MPLS/IP backbone. o Swapped PE and P routers with Huawei routers and switches from other vendors. AVEA IPRAN Project

AVEA is one of the national leading ISP in Turkey, providing nationwide mobile service for their subscribers. I worked for Avea Telecom IPRAN project and the duties involved swapping entire Avea’s network core and access Tellabs routers devices with Huawei NE40-X8-X3 and ATN950-B routers. For the OMC core sites, I deployed NE40-X8 routers between Tellabs, RNC and other devices in the OMC. I handled migrating ports of RNC, Tellabs another devices one by one on to Huawei routers to make sure services are working normal. I used Bgp, Ospf, MP-Bgp and IP/MPLS for OMC core and access sites. This transport technology allows the traffic differentiation and traffic prioritization over a packet network. IP/MPLS also offers traffic convergence over any transmission line such as Microwave, leased lines, Metro Ethernet, SDH Links and etc. For the access sites, I handled migrating services such as Metro Ethernet and SDH Links form the Tellabs device at the access sites to swap the Tellabs device Turkcell TAN Project

o I handled swapping Alcatel routers with Huawei 950B and NE40 routers at Turkcell Mobile Backhaul infrastructure. o Swapped Alcatel routers with Huawei 950B at POP locations and Huawei NE40 x8 at central locations. o Provided high availability by using BGP routing and RSVP-TE explicit paths. o Implemented MPLS IP backbone between POPs and central location. o Implemented MPLS L3VPN and MP-BGP.

o Implemented QoS for voice traffic over MPLS IP backbone. o Implemented BFD and FRR for fast convergence of routing processes. SUPERONLINE – Seamless MPLS Project (Huawei Technologies) o Provided high availability on corporate customer circuits by using MPLS L2VPN on POP locations. Planning the U-PE swap and rollout operations and implementation of IP technologies. o Swapped Cisco routers with Huawei NE40 routers at every POP location. o Provided high availability by using two L2VPN (Primary and Backup) connections between NE40 routers and Huawei HI switches (L2 termination point).

o Implemented MPLS L2VPN (Martini, VLL, VPLS)

o Implemented MPLS L3VPN and MP-BGP.

o Implemented QoS
