Experienced Network Engineer specializing in enterprise and data center networking, with skilled in routing, switching, firewalls, SD-WAN, Cisco DNA Center, and ACI including the Design, Deployment, and providing network support, installation, and analysis. Led successful deployments and optimizations of Viptela SD-WAN solutions across global branches, integrating intelligent traffic steering, dynamic path selection, and application-aware routing for enhanced performance and reliability. Deployed Palo Alto NGFWs for migration and configuration, along with setting up advanced security policies, NAT, VPN, and threat prevention; enforcing NAC policies through Cisco ISE (802.1X, dynamic VLANs, device profiling); and implementing Cisco DNAC for centralized policy management, SD-Access, and Trust Sec. Cloud networking is configured smoothly across various platforms such as AWS (Transit Gateway, Direct Connect), Microsoft Azure (Traffic Manager, Load Balancer), VMware (vSphere, NSX), and Zscaler (ZIA, ZPA) for secure and efficient connectivity to the cloud and hybrid environments. Managed load balancers in the enterprise space with F5 LTM/GTM, Citrix NetScaler, and A10 Networks, implementing global traffic distribution, SSL termination, and advanced health monitoring, to ensure availability. Deployed Cisco Meraki, Aruba, and Juniper MIST wireless solutions in high-density environments, ensuring RF optimization, VLAN segmentation, and 802.1X authentication. Proficient in network monitoring tools such as Wireshark, SolarWinds, Splunk, and SNMP-based monitor systems. Integrations and fine-tuning were performed with Citrix NetScaler ADC and F5 BIG-IP iRules for GSLB, traffic steering, and SSL/TLS offloading, guaranteeing high availability and seamless application delivery. Implemented and optimized DMVPN, IPsec, and SSL VPNs, applying IKEv2/IPsec with AES-256 encryption on Palo Alto, Juniper SRX, and Cisco ASA firewall for secure remote access. Designed and managed ACI Multi-Site and Multi-Pod architectures enabling disaster recovery, stretched fabrics, and policy consistency across geographically distributed data centers. Network engineer with practical exposure to CF Engine-based configuration generation, focusing on producing structured, deterministic configuration files for large-scale IP and transport networks. Experienced in using CF Engine 2/3 policy structures to translate design intent, provisioning data, and circuit layouts into validated configuration outputs for routers, switches, and optical platforms. Worked on maintaining CF Engine-driven version control, baselines, and naming conventions, ensuring consistent configuration integrity across high-volume network changes. Deployed NGINX and HA Proxy reverse proxies with WAF (Web Application Firewall) integration, enabling SSL offloading, Layer 7 traffic inspection, rate limiting, and application security hardening for enterprise workloads. Specialized in VoIP technologies (CUCM, SIP, QoS) and wireless networking (WLAN controllers, AP deployments, RF optimization). Keywords: ffive South Dakota
