What I'm looking for

I seek senior network and security roles where I can design resilient cloud-hybrid networks, lead SD-WAN and automation initiatives, mentor teams, and deliver secure, high-availability infrastructure at enterprise scale.

I am a Network Infrastructure Specialist with 12+ years of global experience architecting, securing, and operating complex enterprise networks across data centers, branches, and hybrid cloud platforms (AWS, Azure, OCI). I deliver high-availability designs, SD-WAN rollouts, cloud connectivity, and VoIP collaboration solutions using Cisco, Juniper, Palo Alto, Fortinet, VMware, and Microsoft technologies.

I have led SD-WAN deployments, Zero Trust integrations, migrations to cloud with ALB/WAF, and large-scale network integrations for acquisitions and new offices; I also manage vendor procurement, BOQs/POs, and compliance activities. I mentor and lead teams of network administrators and IT engineers while driving incident/change management, monitoring, and proactive remediation.

I focus on automation and repeatable operations using Python, Ansible, Terraform, and REST APIs, and I hold multiple cloud, security, and networking certifications including CCNP Enterprise, Fortinet, Oracle Cloud, AWS Cloud Practitioner, and VMware credentials.
