Cloud Native Operations and Enablement (CNOE) - Bluemix to AKS Migration-> Developed and maintained a shared library in Groovy to streamline CI/CD processes for various types of applications (e.g. JAVA, NodeJs, .Net, Python) across multiple projects. This involved creating reusable functions, classes, and utilities that encapsulated common tasks such as code compilation, testing, artifact management, and deployment.-> Supporting enterprise-wide migration to Microsoft's Azure public cloud through development of Jenkins Shared Libraries, containerization and security integrations such as TideLift and PrismaScanner.-> Integrated Twistlock into the CI/CD pipeline to scan container images for vulnerabilities and policy violations during the build process. Configured hooks or plugins within the build system called Jenkins to trigger Twistlock scans and enforce security checks.-> Collaborating with infrastructure and networking teams to troubleshoot and resolve issues related to AKS cluster setup, networking configurations, ingress controllers, or other infrastructure-related components impacting deployments.-> Engaging with the team FOTF (Factory Of The Future) to implement and integrate custom GitHub Actions workflows to replace existing CI/CD pipelines in Jenkins, leveraging the power and flexibility of GitHub Actions for continuous integration and CD processes which involves in python custom scripts.-> Providing support and guidance to teams utilizing Red Hat's cloud platform, such as Red Hat OpenShift or Red Hat OpenStack, for their shared library and deployment needs. Assisted teams in configuring and utilizing the shared library within their CI/CD pipelines on the Red Hat cloud.-> Acting as a primary point of contact for handling production calls, serving as the first responder to address and resolve critical issues reported by stakeholders or end-users.-> Engaging different POC's and pilot testing with different tools like Thereat modeler, OPA.

-> Implemented ansible playbooks for deploying to Kubernetes which are integrated in shared library. Integrated Kubernetes with Hashicorp Vault to inject configurations at runtime for each service using init, config sidecars and persistent volume sharing between app and config containers.-> Converted existing AWS infrastructure to serverless architecture (AWS Lambda, Kinesis) deployed via Terraform & AWS Cloud formation.-> Worked with RedHat OpenShift Container Platform for Docker and Kubernetes . Used Kubernetes to deploy scale, load balance, scale and manage Docker containers with multiple namespace versions. -> Written Chef Recipes to automate our build/deployment process and do an overall process improvement to any manual process. Setup and maintained automated environment using Chef Recipes within AWS environment. Good understanding of Knife, Chef Bootstrap process etc.-> Used Version Control tool, SVN to create branches and implement parallel development process. Implemented a GIT mirror for SVN repository, which enables users to use both GIT and SVN. Developed automation scripting in Python (core) using Chef to deploy and manage Java applications across Linux servers.

-> Engaged and Collaborated with the Rules Designer and Decision Center to develop, test, and deploy business rules effectively and to gather requirements and break them down into functional stories for manual testing and regression suite automation.-> Promoted the automation of regression test cases using tools like SOAP UI Pro and JMeter, resulting in reduced execution time and improved resource utilization. Additionally, I prepared enhancement designs and presented them to the business and other teams involved, facilitating effective collaboration and alignment.-> Managed the Business Object Model (BOM) and Execution Object Model (XOM) to ensure reusability and maintain consistent terminology for rules. Additionally, I designed and developed J2EE interfaces to populate the Execution Object Model. I was involved in designing and authoring rules, as well as orchestrating the rule flow. Furthermore, I designed and developed dynamic domains for rule authoring purposes.-> Involved in writing the rules for Implemented CI/CD web hooks & workflows around Jenkins to automate the dev test deploy workflow around Puppet codebase. Installed and Managed Jenkins and Nexus for CI and Sharing Artifacts respectively within the company.

-> Contributed to Azure Governance policies by working on them and automating processes using PowerShell scripting and Involved in managing Azure IaaS virtual machines (VMs) and Cloud services (PaaS role instances) into secure VNets and subnets, designed VNets and subscriptions to conform to Azure Network Limits.-> implemented the integration between Azure and ServiceNow, enabling the notification of Azure Service Health alerts and the automatic creation of incidents in ServiceNow using REST API.-> Deploying and managing applications utilizing Spinnaker, an open-source Continuous Delivery (CD) platform. Within Spinnaker pipelines, utilized Groovy to customize and extend deployment workflows.-> Implemented Groovy scripts to incorporate conditional logic, iterations, and dynamic configurations, enabling flexible and dynamic deployment processes.-> involved in working with tools such as Cloud Health to manage the cost of Azure cloud services. This includes analyzing and taking steps to reduce costs by utilizing recommended Reserved Instances (RI) suggested by Cloud Health. Additionally, focused on cost management in Azure, implementing measures for cost savings. To streamline reporting processes, I have automated weekly reports for all teams using PowerShell.

As a DevOps Engineer, I have worked extensively with a variety of proprietary and open-source tools such as Jenkins, Gerrit, AWS, JIRA, and more for development and deployment purposes. My responsibilities included monitoring and maintaining AWS S3 buckets that stored build artifacts, configuring and managing AWS Lambda functions, and utilizing Route53 for traffic routing across different regions. I also managed a data warehouse using Amazon RedShift, migrated infrastructure to a serverless architecture, and implemented Azure Active Directory and Role-based Access Control for SaaS applications. I configured Azure Runbooks for automation, worked with Azure blobs for storing unstructured data, and collaborated with parallel DevOps teams within the organization. Troubleshooting, Docker container management, CI/CD implementation, configuration management with Chef, ELK stack setup, TFS to Git migration, and shell scripting were also part of my expertise and responsibilities.
