Message

I've supported enterprise Palo Alto Networks customers at Movate, troubleshooting NGFW and Panorama policies, NAT, routing, VPNs, and traffic-flow behavior in mission-critical environments.

I work across AWS-hosted and hybrid architectures, resolving IPsec and GlobalProtect VPN issues, SSL decryption problems, connectivity incidents, and security-policy requirements using logs, packet captures, and CLI analysis.

Previously, I delivered Tier 2 TAC support for Calix platforms and network devices, and supported Cisco 4G/LTE, QoS, routing, cable modem, and DOCSIS issues. I bring 5+ years in SLA-driven support environments and communicate clearly with customers, engineering teams, and technical stakeholders.
