1)Implemented and managing the Kubernetes cluster including deployment, scaling and ensure smooth operation of all deployed pods. 2) Diagnosed and resolve issues with k8s pods in non-running state such as CrashLoopBackOff, Pending, ImagePullBackOff, and Evicted state. 3)Generated Telecom core node as VNFD'S and NSD'S from Yaml files converted from client provided Tosca templates. 4)Worked on the Cloud platform (Openstack) to deploy and manage the applications. 5)Using our application, I run and manage the telecom core node packages as VMs [NS - Network Service] in Openstack server. 6)Ensure the uptime of the VM’s (Virtual Machine) by providing features such as high availability,manual and auto scaling [both vertical and horizontal] and Healing. 7)Fine-tune and resolve issues that come up while launching these NS when they go to unfavorable states like Scheduled and Failed state. 8)Collaborated with development team to debug and fix application issues. 9)Expertise in OSM Architecture by diagnosing and ensuring the uptime of the various application pods such as database pods[ Kafka, MongoDB, MariaDB] and deployment pods[RO, LCM, NBI, POL, etc...]. ACHIEVEMENTS 1)Successfully deployed the Production BSNL Zonal Node Orchestrator [TEOSM] based on OSM (Open Source MANO) across multiple locations in India. 2)Performed the installation on top of a bare metal server by spawning VM’s (Virtual Machines) and installed required prerequisites and packages by utilising docker and managing it with Kubernetes. 3) Led the end-to-end deployment in a completely offline, isolated environment, ensuring seamless integration and functionality without internet access. 4)Explored and contributed to the development of a monitoring framework called Zabbix which is used for monitoring essential KPI health markers and for providing instantaneous alerts over MS Teams and Outlook and other media platforms.
