About Lavanya I.

I am a senior network engineer with 9+ years of real-time, hands-on experience designing, implementing, securing, and operating enterprise-scale network infrastructures across data centers, WAN, wireless, cloud, and security environments. I have worked in high-availability, production-critical networks where uptime, performance, and security are business-critical.My expertise spans end-to-end network ownership—from architecture and design to deployment, automation, troubleshooting, and optimization. I specialize in modernizing legacy infrastructures and delivering secure, scalable, and cloud-ready networks for large enterprises.I bring deep technical experience across routing and switching (BGP, OSPF, EIGRP, IS-IS), high-availability designs (HSRP, VRRP, GLBP), data center architectures (spine-leaf, VXLAN, EVPN, Cisco ACI), and WAN/SD-WAN transformations using Cisco Viptela and Versa. I have led migrations from MPLS and DM-VPN to SD-WAN, significantly improving resiliency, visibility, and performance.On the security side, I have extensive hands-on experience with Palo Alto Networks, Cisco Firepower/ASA, Prisma Access, Zscaler ZIA/ZPA, IDS/IPS, PKI, VPNs, and Zero Trust architectures. I’ve designed and managed DMZs, perimeter firewalls, secure remote access, and cloud-based security platforms integrated with Azure AD SSO.I also work heavily in hybrid cloud networking, building and integrating environments across AWS and Azure, and automating infrastructure using Terraform, Ansible, and Python. Automation is a core focus of my work, helping reduce manual errors and accelerate service delivery.Additionally, I design and support large-scale enterprise wireless networks using Cisco SDA, DNAC, Catalyst 9800, ISE, Meraki, and Aruba Central, including RF design and global deployments. I’ve delivered application traffic management and load balancing using F5 BIG-IP (LTM, GTM, APM) across on-prem and cloud environments.I’m known for being deeply technical, calm during high-severity incidents, and dependable in complex environments. I collaborate closely with cross-functional teams and vendors to deliver secure, resilient, and future-ready network solutions.Core Focus: Enterprise Networking | Network Security | SD-WAN | Hybrid Cloud | Automation | Zero Trust
