Summary
Dynamic and results-driven Network Engineer with over 4 years of progressive experience architecting, securing, and optimizing enterprise-grade network infrastructures across on-premises and cloud environments. Proven ability to deliver high-performance, scalable, and secure networks leveraging technologies such as Cisco Nexus/Catalyst, Palo Alto NGFW, F5, SD-WAN (Viptela), and Zero Trust frameworks (Zscaler ZIA/ZPA).
Hands-on expertise in network automation using Python, Ansible, and Terraform, driving infrastructure-as-code (IaC) practices for scalable deployments and reducing human error. Adept in routing and switching protocols (OSPF, BGP, EIGRP, VXLAN, EVPN), load balancing, DNS management (Infoblox), and implementing hybrid connectivity using Azure vWAN, AWS Transit Gateway, and VPN/IPSec tunnels.
Well-versed in implementing zero-trust security models, micro-segmentation, SSL inspection, and granular access controls across firewalls and cloud platforms. Experienced in data center migrations, SDN/ACI environments, and large-scale Wi-Fi deployments (Cisco WLC, Meraki, Aruba). Known for a proactive approach to incident resolution, deep-dive packet-level troubleshooting, and end-to-end delivery of network transformation projects.
Seeking to leverage my technical acumen and problem-solving skills in a forward-thinking organization focused on secure, cloud-native, and automation-driven network operations.
