- Designed and implemented optical communication infrastructure for transit systems with OTDR and OLTS fiber testing, generating certified test reports via Fast Reporter.
- Developed shop, network design, and as-built drawings using AutoCAD and Visio for Layer-2/Layer-3 network infrastructures.
- Integrated AVAYA ERS 4450GTS switches into an existing OSPF environment at 26 remote MTA sites connected to Cisco 3850 switches, ensuring seamless dynamic routing.
- Installed and configured AVAYA 4850 GTS L2/L3 switches, Avaya Fabric Orchestrator servers, and power distribution units in operational networks.
- Configured Low Band and High Band radios for Layer-2 communication and conducted Radio Factory Acceptance Test (RFAT) and Radio Site Acceptance Test (RSAT) for site commissioning.
- Performed software and firmware upgrades for Avaya switches, Palo Alto firewalls, Cisco Meraki appliances, and AFO servers to maintain network resilience and security.
- Planned and executed Site Acceptance Testing (SAT) documentation, covering network discovery, failover testing, component validation, and OSPF routing performance benchmarking.
- Designed, implemented, and upgraded OSPF and EIGRP backbone networks, migrating from Nortel Passport 1648T to AVAYA ERS 5952 GTS switches.
- Deployed BGP configurations for inter-network routing and optimized traffic flow across multiple transit backbone links.
- Created IP addressing and subnetting schemes for multi-site, multi-vendor OSPF, EIGRP, and BGP networks with Layer-2 and Layer-3 devices.
- Drafted phased implementation plans, FAT procedures, and SAT documentation, conducting acceptance testing with authorized NYC Transit personnel.
- Led installation and configuration of Palo Alto Firewalls, Cisco Catalyst/Meraki switches, and Ubiquiti network equipment, ensuring firewall rules and VPNs align with enterprise security policies.
- Performed network monitoring and troubleshooting using tools like PuTTY, Fast Reporter, Nortel EDM, WinSCP (TFTP), Cisco Meraki Dashboard, and Avaya Fabric Orchestrator.
- Oversaw network documentation, escalation replacement project plans, and construction documentation including installation shop drawings and communication bulletins.
- Deployed Cisco Meraki cloud-managed Wi-Fi networks spanning 9 train stations, configuring Access Points (MR77, MR33), Security Appliances (MX100), and Switches (MS210-24P).
- Designed and implemented LAN/WAN networks with redundant firewalls and BGP/MPLS mesh VPN topologies to ensure high availability and disaster recovery.
- Maintained operational integrity of live transit networks during upgrades, verifying end-to-end OSPF and BGP routing convergence and connectivity.
- Performed Active Directory audits, security group management, OU structure creation, and Group Policy enforcement in hybrid network environments.
- Monitored network performance metrics (uptime, latency, throughput, SNMP-enabled device status) and diagnosed bandwidth hogs and firmware issues using network management tools and logs.
