Hello there, netizen!

I am an experienced & versatile Software Engineer involved in hands-on development and problem solving in an agile environment since a long time. I'm passionate about technology and its impact on society at large.

I have professional work experience in full stack mobile and web development. Apart from that I have keen interest in the following domains: Cyber-physical systems (CPS)/IoT, distributed consensus/Blockchain, Software Defined Networking, AI, ML, Embedded Sensor Fusion, 3D printing, Augmented Reality.

I am currently pursuing MS in CS (Networking) @ University of Southern California.

You can find me at local hackathons in the physical realm or below handles in the virtual realm.

                    

Cheers

Software Engineer 3 [ Feb 2022 - Present ]
   Developing automated solutions for K8s managed product: Cisco Intersight
   Worked on various subsystems of Intersight namely Intersight Workload Optimiser, Intersight container orchestrator, Intersight Kubernetes Service etc. Different subsystems focus on managing different aspects of hybrid cloud operations which include but not limited to: UI workflow creators, device inventory management, server rack health monitoring, telemetry etc. These functionalities are developed across 100+ micro-services primarily in Go and a few in nodejs and Java.

SDN and Software Automation Engineer Co-Op [ May 2021 - Dec 2021 ]
   Developed custom control loop to maintain desired state of K8s cluster with multiple VMs and SR-Linux Routers. A typical Clos topology has multiple DC gateways connected to spine routers which in turn are connected to leaf routers. Below the leaf there are workload VMs. All of this formed the K8s cluster wherein I developed a daemonset which runs a custom container image as a pod on each node. This custom docker image contained python code to detect new service being added into the cluster and then trigger LLDP (Local Link Discovery Protocol) to find the neighboring leaf and make subsequent GNMI calls to it to update its routing table and other configurations.
  In addition, developed a web portal with in-browser console and drag drop functionality to configure and auto-deploy a given Clos topology
  Contributed towards K8s YAML generation with GPT-3’s NLP for predefined scenarios of Telco & Web-scale DC cloud topologies.
