With over 25 years of experience as a network engineer, I have developed extensive expertise in designing, managing, and troubleshooting complex networks across a wide range of platforms. My proficiency spans Linux distributions, all versions of Windows, and various networking hardware, including Cisco IOS/IOS-XR/XE routers, Nexus systems, Juniper JunOS routers, and Nokia GPON chassis. I specialize in configuring advanced firewalls such as Cisco Firepower, Palo Alto, and Checkpoint, as well as load balancers like F5 GTM/LTM appliances. Additionally, I am highly skilled in packet captures, deep packet inspection, and log analysis, using tools like Wireshark, OmniPeek, Splunk, and Nagios to ensure optimal network performance.My expertise includes a comprehensive understanding of Layer 1-7 protocols, including Ethernet, MPLS, BGP, IPv6, and VPN technologies such as IPSEC and DMVPN. I also have experience with cloud networking and integration in platforms like AWS and Azure, as well as orchestration tools for network management. While quite knowledgeable in scripting languages like Ruby and Python for automation and task optimization, my focus remains on network engineering, ensuring robust, secure, and high-performance infrastructures that align with organizational needs.
