Plan and execute HA failover testing, PAN-OS upgrades, disaster-recovery exercises, and maintenance procedures while minimizing service impact.
Troubleshoot HA infrastructure dependencies, including cables, transceivers, switch ports, port channels, VLANs, routing, MTU, latency, packet loss, and redundant-path failures.
Lead the configuration, support, and troubleshooting of Cisco Catalyst and Nexus switching environments.

Diagnoses complex connectivity and performance issues through firewall logs, session inspection, packet captures, CLI diagnostics, switch counters, flow data, and network-monitoring platforms.
Analyze TCP/IP behavior, including handshake failures, SYN/SYN-ACK/ACK flow, retransmissions, resets, timeouts, asymmetric routing, MTU/MSS issues, fragmentation, latency, packet loss, and NAT translation problems.
Verify packet flow across firewall policy, App-ID, routing, NAT, decryption, threat prevention, VPN, switching, and server/application layers.
Monitor firewall management-plane and dataplane health, including CPU, memory, session capacity, packet buffers, throughput, logging, and interface performance.
Integrate Palo Alto NGFWs and Panorama with Strata Logging Service and Cortex XSIAM.
Ensure reliable firewall log forwarding, cloud logging, log ingestion, data normalization, event availability, retention, and telemetry quality.
Use Cortex XSIAM and XQL Search to investigate, correlate, and respond to firewall, endpoint, identity, cloud, and third-party security events.
Partner with SOC teams to tune detections, investigate alerts, develop response procedures, improve visibility, and support incident containment and remediation.
Lead root-cause analyses for major network or security incidents and deliver corrective and preventive action plans.
Develop and maintain network diagrams, firewall-policy documentation, HA designs, runbooks, change plans, architecture standards, and operational procedures.
Mentor junior engineers and provide technical leadership during projects, production incidents, and security reviews.
