🚀 Building Scalable & Reliable Infrastructure

• Designed, built, and maintained cloud-native platforms to support scalable applications and services.
• Developed automation tools and CI/CD pipelines to streamline deployments and reduce downtime.
• Improved system reliability, observability, and performance through proactive monitoring and incident response.

🛠 DevOps & Infrastructure as Code (IaC)

• Implemented Infrastructure as Code (IaC) using tools like Terraform, Ansible, or CloudFormation.
• Managed Kubernetes clusters and containerized workloads to optimize application delivery.
• Collaborated with software development and operations teams to enhance platform resilience and security.

🔍 Performance Optimization & Security

• Optimized cloud and on-prem infrastructure for cost efficiency and high availability.
• Enforced security best practices, ensuring compliance with industry standards.
• Troubleshot and resolved infrastructure issues, minimizing downtime and improving system reliability.

• Experienced in provisioning AWS EC2 instances and associated services using Terraform IAC
• Collaborating with teams to set up CI/CD pipelines using Jenkins and AWS CodePipeline
• Implementing continuous integration, continuous deployment pipeline (CI/CD) with Git, Maven, SonarQube, Nexus, and Tomcat, Jenkins Ansible Docker, Terraform and Kubernetes
• Integrated webhooks build triggers on SCM into Jenkins to automate the code check-out process immediately a code change is push to the repository
• Apply Git best practice by assigning ONLY required permissions to developers and enforcing best branching strategy
• Managed multi-tier application and configured Route 53 to route traffic to backend application through ELB and Nginx Ingress Controller
• Oversees the deployment of applications from a Monolithic architecture to a Micro-services architecture
• Designing, installing, and implementing Ansible configuration management system, writes, modify and maintain Ansible playbooks (Jenkins pipeline scripts (declarative and scripted), Kubernetes manifest files using Helm, Docker file, and Bash Shell Scripting) for automatic configuration management using CI/CD
• Using Ansible playbooks, roles, and ad-hoc commands to perform configuration management, patching, CI/CD deployment, and security management
• Configuring docker containers, developing docker files for a different environment, tagging and pushing docker images to docker private registry
• Did Jenkins NewRelic, Prometheus/Grafana integration used for application performance monitoring and alerting using Helm in a Kubernetes cluster
• Configured and managed Kubernetes EKS and self-managed Kubernetes Kubeadm and Kops
• Managing containerized application using Kubernetes objects; nodes, pods, deployments, RS, RC, stateful sets, DaemonSet, Persistent Volume, storage classes, Resouce Quota, nameSpaces
• Exposing applications using various service discovery like ClusterIP, NodePort, Load Balancers, ExternalName, and Ngnix-ingress

• Administration of GitHub created branches, repositories, teams and give access permissions to team members and created enabling environment for developers to commit their codes
• Performed build and release of all software cycles engineering, test, production, update, patches, and maintenance
• Designed, built, automated build/release of software from development to production environment that also satisfies the internal audit and compliance
• Created users, repositories, branches, tagging, patch fixes, pull request, and trained users on the Git version control system
• Automate provisioning of infrastructure in AWS using Terraform and Ansible with Dynamic inventory
• Created Docker files and built images and push to the Docker registry
• Configured and managed highly available and scalable Kubernetes cluster for containerized applications and exposed it to end users using various services like DNS, ELB, NodePort, Ingres Controllers and Auto Scaling etc
• Setup Auto scaling groups based on memory and CPU to adapt to unforeseen spikes without having an outage or needing manual intervention
• Performance testing for complex systems, Build Release, and environment planning, designing, implementation for projects across different technologies
