Definition development strategy of LAN/WAN, Data Centers LAN for Inter RAO Group as a whole, and for each subsidiary specifically. Supervision of network building/development projects, the key role in idea generation, design approach and hardware selection for each site. Estimation network infrastructures in efficiency, security, and disaster recovery areas. Heterogeneous network incidents analysis and problem solving. Generation conceptual/logical architectures, system documents, test plans, and risk assessments.
Implementation and Tier 3 support of complex network topologies including routers, switches, firewalls and wireless systems. Leading networking teams, in the Headquarters and in the affiliated companies.
Accomplishments:
o Designed and implemented multitenant Enterprise Data Center based on Cisco Nexus hardware, was started one year earlier than expected;
o Actively involved in project of building resilient and distributed system of enterprise Data Centers and creation of Private Cloud with emphasis on network virtualization;
o Implemented Points of Presence (PoP) and Transit Network Nodes on Internet Exchanges such as MSK-IX allows to provide services to customers through anyone ISP;
o Enterprise MPLS VPN technology implemented in the Headquarter campus and in the backbone networks, made available to increase network security without usage additional firewalls, therefore cost of project has been decreased;
o Organized disaster tolerant network nodes on Power Plants and Power Trading Companies. Implemented standardized configuration streamline troubleshooting operations and hardware interchanging;
o Successfully completed research in abilities of NGFWs of different vendors, the most suitable platform was selected.
o Completed security assessment of usage Internet resources, as a result Internet access was secured, based on User-ID and Application ID provided by Next-Generation Firewalls (NGFW) Palo Alto Networks which were integrated;
o Full cycle of migration of network infrastructure and data resources to new network environment with consistent IP address plan were realized;
