About

Professional summary

I am a Senior Network Specialist with more than 17 years of experience designing, implementing, operating, and supporting large-scale enterprise WAN and network environments. My expertise spans SD-WAN, L2/L3 networking, routing and switching, network security, and enterprise operations.

I have hands-on experience with Cisco, Juniper, Versa, Viptela, Meraki, SilverPeak, FortiGate, Palo Alto, and F5 technologies. I work extensively with routing protocols and services including BGP, OSPF, MPLS, LDP, NAT/PAT, IPv6, VPNs, ACLs, and IPS/IDS.

In my current role, I configure and troubleshoot enterprise SD-WAN platforms, support firewall and routing infrastructure, resolve complex incidents, perform root-cause analysis, and manage escalations. I use service management and network monitoring platforms to ensure timely resolution and stable circuit operations.

I have supported large enterprise customer environments, including Fortune 500 organizations, and have led operational activities involving high-volume ticket handling, license and certificate renewals, documentation, and weekend operations. I am comfortable coordinating with ISPs, vendors, customers, and internal technical teams.

I also have leadership experience managing distributed engineering teams and mentoring junior engineers. I have implemented ISO 27001:2013 controls across network sites and remain focused on secure, resilient, and well-documented network operations.

I hold Cisco and Juniper networking certifications, including CCNP, CCNA, JNCIS-SP, and JNCIA. I am interested in senior network engineering and SD-WAN operations opportunities where I can apply my technical expertise and leadership experience.
