PROFESSIONAL EXPERIENCE:

Confidential, Palo Alto, CA

SENIOR NETWORK ENGINEER

Responsibilities:

• Managed Enterprise Core and Datacenter migration from legacy Cisco Catalyst infrastructure to Nexus-based hierarchical network model using 7000, 5500 and 2000 FEX switches.
• Developed and executed Access switch replacement project for 30 buildings and over 75 data closets. Managed multiple deployment teams to minimize business impact and complete ahead of schedule.
• Migrated Enterprise firewalls from Juniper to Palo Alto Networks using Panorama-managed 5000, 3000 and 200 series firewalls to provide a modular, dynamic, application layer aware security model.
• Resolved network performance, availability and administration issues by unifying the routing domains with OSPF/BGP and implementing a stringent end-to-end QoS model.
• Implemented geographically diverse Internet edge enabling deployment of high availability site-to-site VPN services architecture to support AWS, Customer, B2B and WAN backup connectivity with per-tunnel QoS, routing and access policies.
• Integrated Enterprise with AWS (Amazon Web Services) for internal and external stakeholder use.
• Created new revenue stream by providing complete network packages for customers' Ground Control Systems Networks as part of satellite campaigns. Typical network package included LAN/WAN/Firewalls/Remote Access/NMS for 5 to 25 sites. Concurrently managed multiple onsite teams at multiple sites to install, validate and execute all customer witnessed sight acceptance testing (SAT).
• Created ECATS (Emergency Commanding and Telemetry System) for Mission Control. This system provides a complete, transport agnostic mobile command center to ensure mission continuity in the event of a multiple control site disaster.
• Designed network staging and validation lab. Currently used for provisioning automation pilot, leaf-spine pilot and customer witnessed Ground Control Systems field acceptance testing (FAT).

SENIOR NETWORK ENGINEER

Responsibilities:

• Integrated international, cross-continental networks into a single centralized system; provided a self-healing, homogeneous, secure network able to transport voice, signaling, and data.
• Strengthened connectivity and diversity while lowering costs of legacy systems by leveraging newly integrated network to provide inter-site revenue VoIP trunks. Slashed costs even further by leading migration of global legacy SS7 signaling network to SS7oIP.
• Saved $250,000 while providing an IP-based, feature-rich platform by migrating outdated Alcatel STPs to Cisco ITPs.
• Opened the door for creation of new revenue stream by developing routing and security infrastructure that permitted development of Confidential Static IP service (GSIP).
• Enabled dynamic secondary/tertiary backup to WAN transport for revenue voice, data and administrative networks by managing global design and deployment of Internet-based site-to-site VPN communications.
• Unified corporate telephony systems worldwide by integrating existing PBX systems using VoIP and replacing branch office systems to provide corporate 4-digit dialing, toll bypass, and circuit elimination.
• Resolved data network routing and performance problems by optimizing configuration of networks, including OSPF, EIGRP and BGP routing protocols, NAT and DNS configuration, and proactive identification of failing platforms.
• Refined content delivery and bandwidth utilization by effectively deploying a combination of traffic shaping, traffic policing, policy-based routing, and SLAs with EOT (Enhanced Object Tracking).
