I am working on a project to develop a comprehensive, open-source solution for Kubernetes (K8s) orchestration across a multi-cloud platform. The solution integrates a variety of tools and technologies to deliver a scalable, efficient, and secure K8s environment. As part of this initiative, we utilize RKE2, Rancher, GitLab, Harbor, Helm Charts, Infrastructure as Code (IaC) with Terraform, and manage Day 2 services to ensure seamless operations and scalability.

Few of the key responsibilities are listed below.

• Automated infrastructure provisioning and configuration using Terraform and Ansible to streamline resource deployment and management.
• Deployed and configured Rancher environments to manage Kubernetes clusters effectively.
• Designed and developed CI/CD pipelines in GitLab to automate software builds, testing, and deployment processes, ensuring consistency and reliability across multiple projects.
• Designed and implemented authentication and authorization schemes across platform services and applications using Keycloak, OpenLDAP, and Terraform, integrating with operations Keycloak and LDAP systems.
• Created cloud platforms on OTC for Kubernetes cluster deployment, enabling efficient multi-cloud environments.
• Implemented and configured Renovate Bot within the project to automate updates for container images and Terraform provider versions.
• Developed and implemented Packer pipelines for OS image hardening and customization, specifically for Kubernetes nodes.
• Conducted Proof of Concept (POC) for Rancher Observability-StackState, enabling multi-cluster observability within RKE2 environments.
• Implemented pipeline for Docker image lifecycle management, including build, scan, tag, and push processes.
• Integrated Software Bill of Materials (SBOM) using Trivy to ensure secure and compliant software components.
• Set up automated GitLab processes for commits, merges, and tagging, including automation for auto-merge and tagging upon merge request approval.
• Developed automation to generate release notes based on Git tags, streamlining the release process.
• Created an architecture diagram to represent the complete deployment process, providing a clear and comprehensive visual overview of the workflow and the components involved in the deployment.
• Support the Operations team.

• Design and develop workflows in HPOO as per the requirements.
• Analysis of the workflows developed, and provide suggestions on any improvements that can increase the performance and efficiency of the system, and reduce the number of incidents.
• Analysis of incident reports to reduce the failure occurrences.
• Conduct post-incident reviews (PIRs) to analyze root causes, identify areas for improvement, and implement preventive measures.
• Designing workflows in JIRA for EPICs and stories.

• Configuring and managing the security for mail servers.
• Troubleshooting the issues related to the customer mail servers.
• Managing various Linux distributions, such as Red Hat and Debian, including installation, configuration, and troubleshooting.
• Automation using shell scripting.

• Managing various Linux distributions, including installation, configuration, and troubleshooting.
• Troubleshooting system issues, performance bottlenecks, and network connectivity problems using command-line tools and monitoring utilities.
• Storage provisioning, configuration, and management across various storage platforms.
• Designing, deploying, and managing SAN infrastructure, including switches, fabrics, and storage arrays from vendors like EMC and HP.
