Senior Network Engineer, Spotter, Waukesha, United States Jul 2024 – Present

Designed and maintained enterprise network infrastructure focusing on Layer 3 routing protocols (OSPF, EIGRP, BGP) and Layer 2 switching protocols (Spanning Tree, VTP, LACP), implementing network changes and optimizations across LAN/WAN environments to ensure high availability, redundancy, and minimal downtime while managing network reconfigurations, Layer 2 VLAN setups, and Layer 3 subnet modifications.

Specialized in Layer 3 BGP routing (both iBGP and eBGP) optimization and troubleshooting, addressing complex issues like prefix filtering and route flapping to maintain robust WAN connectivity between remote offices and data centers, while ensuring optimal route convergence through strategic OSPF area design and network segment redistribution across Layer 2/Layer 3 boundaries.

Administered core network services including DHCP and DNS infrastructure at Layer 3, managing IP address allocation, preventing conflicts, and maintaining failover systems to ensure continuous and reliable network operations across the enterprise while implementing Layer 2 switching optimizations.

Implemented comprehensive Layer 3 VPN solutions (IPsec, SSL VPN) and SD-WAN infrastructure, optimizing WAN performance while reducing MPLS costs through dynamic path selection and enhanced network visibility across multiple sites with Layer 2/Layer 3 integration.

Managed Palo Alto Networks next-generation Layer 4-7 firewalls using Panorama and Strata Cloud Manager, implementing centralized policy management, advanced threat prevention, and security compliance measures while integrating with third-party solutions for enhanced operational efficiency and deep packet inspection.

Deployed and optimized Layer 4-7 load balancing solutions (F5, A10, HAProxy) by configuring server pools, virtual IPs, Layer 3 routing protocols, and NAT rules to ensure high availability and efficient traffic distribution for critical web applications with health monitoring.

Conducted proactive network health monitoring and performance optimization of Layer 2-7 infrastructure components (switches, routers, load balancers, firewalls), implementing regular tuning activities to maintain high throughput and minimal latency while managing firewall rules and ACL configurations.

Led cross-functional collaboration with IT teams (systems, security, applications) to integrate Layer 2-7 network services with organizational infrastructure, including hybrid cloud environments and third-party services, ensuring seamless integration and optimal performance across the network stack. Network Engineer, Verizon, Dallas, United States Jun 2023 – Jul 2024

Experience Transfer web services from Cisco CSS platform to F5 Big IP LTM platform.

Maintaining Checkpoint security policies including NAT, VPN and Secure Remote access

Configuring IPSEC VPN (Site-Site to Remote Access) on SRX series firewalls.

Worked as a part of data center deployment where we converted from Cisco 6500 to Nexus.

Designed different VISIO Diagrams for different DMZ Networks to create dashboards and other activities.

Designed and deployed and decommissioned VLANs on core ASR 9K, Nexus 7K, 5K and its downstream devices.

Coordinating with Service providers & Clients on various implementations

Provided testing for network connectivity before and after install/upgrade

Switching related tasks included implementing VLANS and configuring ISL trunk on Fast-Ethernet and Gigabit Ethernet channel between switches.

Performed Partner net re-certification for different users and partner net cleanup for any connect users and S2S VPN Tunnels.

Network Engineer, Mahaveer Finance India Limited, Hyderabad, India May 2020 – Aug 2022

Maintained and optimized enterprise network infrastructure across both LAN and WAN environments, including routers, switches, firewalls, and load balancers, ensuring continuous operation of core routing protocols including OSPF, EIGRP, and BGP while implementing QoS policies and link aggregation (LACP) for increased bandwidth and redundancy.

Designed and implemented F5 BIG-IP and Citrix NetScaler load balancing solutions, configuring advanced features such as SSL offloading, content switching, health monitoring, and maintaining load balancer clusters in active-active and active- passive configurations with session persistence and connection pooling capabilities.

Orchestrated global server load balancing (GSLB) implementations across multiple data centers, while deploying Application Delivery Controllers (ADCs) for advanced traffic management including TCP multiplexing, HTTP compression, and caching, resulting in optimized user experience and improved application response times.

Implemented Layer 4-7 load balancing policies including URL-based routing, content switching, and SSL/TLS termination, along with advanced algorithms such as round-robin, least connections, and weighted response time to optimize traffic distribution across server farms.

Managed routing with OSPF and EIGRP, ensuring redundancy and fault tolerance between multiple office locations and data centers, while implementing VLAN reconfigurations to optimize network segmentation, reduce broadcast traffic, and enhance security across both LAN and WAN environments.

Monitored network performance using tools like SolarWinds, PRTG, Wireshark, Nagios, and Cacti to analyze traffic patterns, identify bottlenecks, and proactively resolve network issues, while actively participating in change management processes for network adjustments, firmware upgrades, and configuration changes to maintain consistent uptime.
