About

I am a software engineer with experience spanning from 2020 to the present, currently working as a Staff Software Engineer at SONICWALL. Over these years, I have developed expertise in network virtualization and traffic management across multiple companies in India. My work involves developing VXLAN support and syslog architecture for IPv6 at SONICWALL, enhancing QoS congestion control and Packet Forwarding Engine features at Juniper Networks, and implementing optical network management solutions at Cisco. I use technologies such as C, C++, Python, Linux, Claude AI, IOS-XR, Junos OS, and various networking protocols including VXLAN, TCP, UDP, TLS, and IPv6.
