About Sumith Kumar

As a Network Engineer with over 8 years of experience, I have managed and troubleshot Aruba access points, Cradle Point devices, and NET Cloud for secure wireless connectivity, deploying Aruba VPN solutions to ensure robust network access. I led a data center migration from Cisco 6500 to Nexus, configured FCoE on Nexus 5548, and installed Palo Alto PA-3060 firewalls, demonstrating my expertise in network infrastructure upgrades. I have designed zero-trust access solutions with Zscaler, implemented AWS IAM policies, and configured VPNs across Cisco, Juniper, and Fortinet platforms. By automating network monitoring and security protocols with Ansible and Python, I enhanced efficiency and improved risk detection. My work included optimizing firewall rules for Cisco Meraki devices and collaborating on F5 Viprion load balancer configurations to enhance reliability and performance. I installed Aruba Secure office cabling and used Aruba AirWave to increase wireless network reliability, reducing support requests. Additionally, I implemented ACI policies and integrated Cisco ACI with VMware and Hyper-V for virtualization, monitoring network performance with Arista telemetry tools to ensure optimal operation.
