Designed, deployed, and managed Kubernetes cluster to ensure high availability, scalability, and optimal performance for containerized applications.Managed deployments using Helm charts and GitOps workflows, ensuring streamlined CI/CD processes for containerized workloads. Provisioned and maintained AWS infrastructure using Terraform (with Terragrunt wrapper), automating the creation of complex, interdependent cloud resources.Defining Infrastructure as Code (IaC) to manage services such as EC2, S3, RDS, VPCs, IAM roles, security groups, and EKS clusters and also leveraged Terragrunt to promote modularization, enforce best practices, and streamline state management across multiple environments (dev, staging, production). Led the migration of critical applications (Gradle, Prometheus, Git-Cache, Jenkins agents) from EC2 instances to Kubernetes.Containerizing applications using Docker, writing optimized Kubernetes manifests (Deployments, StatefulSets, Services, ConfigMaps, and Secrets), and orchestrating workloads using Helm charts. Automated the provisioning of macOS EC2 instances with pre-baked AMIs using Ansible, enabling dynamic scaling based on demand. Secured sensitive credentials within Jenkins environments using AWS Secrets Manager, enhancing security and compliance. Developed and optimized release pipelines in CloudBees CD (CBCD) to align with Jenkins workflows, simplifying release management. Designed and implemented multiple Jenkins pipelines to automate the build and deployment of mobile applications to Microsoft App Center. Successfully migrated Nexus 2 to Nexus 3, ensuring data integrity while coordinating with multiple teams to minimize downtime. Implemented security best practices across infrastructure and application lifecycles, ensuring compliance and reducing risk. Contributed to a proof of concept (PoC) for building an in-house alternative to Microsoft App Center, leveraging cloud-native solutions.
