My DevOps Journey
Welcome to my online portfolio showcasing my experience in DevOps, Operations, and Development.
DevOps Experience ∞
- Implemented Kubernetes cluster migrations from AKS to EKS and performed node migrations within AKS, achieving a 40% cost reduction and automated microservice deployment process to Kubernetes cluster using Jenkins, reducing deployment time by 80%, reducing manual errors by 95% and improved availability to 99%.
- Executed seamless Kubernetes cluster patching for the DRM application using kubeadm, ensuring high availability and minimizing disruption.
- Migrated DRM application, MS SQL server 2012 from Onprem to EKS cluster improving data processing speed by 80% supported faster finance reporting.
- Creation of standard pipelines for C++, Python, C# in Jenkins/Gitlab using SCM as Bitbucket and Managed the migration of the applications like Confluence, Jira, SonarQube, Artifactory, Jenkins, DNS, SVN and Bitbucket.
- Achieved $24,000 in license cost savings by migrating code quality scanners across 5 million lines of code and integrating report publication to the Katapult Dashboard within a Gitlab from Bitbucket workflow.
- Creating a CI/CD pipeline for 5 applications using Jenkins, Sonar, docker hub and deployed to Kubernetes environment.
- Built CI/CD pipeline to create environment and deploy latest version to run sanity & regression suites in EC2, Elastic Beanstalk using Bitbucket, Code Build, Code Deploy and Code Pipeline.
- Implemented Ansible playbooks for data collections, local user creation, copying centralized sudoers, changing passwords, Centrify information, Creation of Deployments, and Services over Kubernetes cluster.
- Engineered fully automated Kubernetes cluster creation for Kubeadm helping reducing deployment time and enabling rapid scalability through CI/CD.
Operations Experience ⚙️
- Orchestrated the complex infrastructure merger of a subsidiary company, successfully integrating their SCM, AKS, Azure and scalingo platforms with KPIT's systems, and implemented key process automations to enhance efficiency and reduce operational overhead.
- Proactively managing and securing large-scale AWS Organization accounts using VPC, Subnets, IAM, Secrets Manager, ACM, IPAM, WAF, NACL, Security Groups, Route Tables, Site-to-Site VPN, Customer Gateway, NAT Gateway, Route 53 maintaining high availability through CloudWatch, S3, ASG, and Load Balancers, ensuring continuous service delivery and automated using Lambda functions, alongside migrating services and decommissioning resources resulted in 60% cost savings.
- Managing VM, AKS, Resource Groups, Storage Account, Web app and service plan, Container apps, DNS zone, Front door, ACR, Application Gateway, WAF, Azure Defender, Cosmos DB, NSG, Application Insight, Load Balancers, VM scalesets, etc with deploying, migration, Decommissioning services on Azure.
- Decommissioned 20+ EKS servers which dropped company cost by 40%.
- Handled 20+ microservices infrastructure and Docker container deployments over Kubernetes clusters in Kops, EKS and Kubeadm.
- Handled Netapp upgrade activity which needed a complete downtime for Solaris infrastructure and hardware replacements for Solaris servers.
- Managed AWS cloud environment for Hyperion Application which includes Hyperion components like HFM, Essbase, FDMEE, SQL Server, Financial Reporting, Planning and DRM.
- Accomplished Disaster Recovery planning and testing of Hyperion and Peoplesoft Application in a AWS cloud platform ensuring 99% availability.
- Migrated static webpages to S3/CDN, ensuring 99.99% uptime and supporting a 20% increase in global user traffic.
- Involved in migration of Hyperion application and Peoplesoft application to AWS Cloud services like VPC, Subnets, Load Balancers, Target Groups, EC2 instances, RDS, Route 53.
- Worked with BAU teams for multiple priority incidents on downtime of Hyperion Application with RCA findings, analysis for permanent fixture.
- Involved in Patching, Hardening Decommissioning, AMI creation and Vulnerability Remediation of servers for security enhancements.
Development Experience 💻
- Migrated the standalone application to microservice infrastructure and providing a SAAS product to customer by using Terraform with the committed availability of 99% by monitoring over AKS clusters using helm provided Prometheus and Grafana.
- Streamlined ticket assignment/ILC claiming through automation, empowering the L1 support team to acquire L2 support skills to advance in career path.
- Automated the code version comparison tasks to keep UAT and SIT environment in Sync using ksh Shell Scripts, Power shell Scripts, VBA coding and ALMS, reducing manual efforts by 8 hours per month.
- Developed multiple shell scripts, Tuxedo services and Batches for a Client.
- Automated Weblogic patching by reducing manual errors by 90%.
- Automated OS patching process with scheduled application auto-restart, saved companies operational cost by 80%.
- Developed Perl scripts for FTP and SFTP solutions for Webmethod integration.
