In my role as a DevOps engineer, I took full ownership of the organization's AWS infrastructure and Kubernetes cluster administration. My responsibilities included managing core AWS services like IAM, RDS, API Gateway, and WAF, as well as performing critical EKS upgrades for Kubernetes versions, node groups, and core components like CoreDNS and kube-proxy. Recognizing that all environments (UAT and PROD) were originally provisioned manually, I spearheaded the adoption of Infrastructure as Code (IaC) by introducing Terraform. I authored comprehensive Terraform configurations to define the platform's infrastructure and successfully imported the existing, manually created resources into this new state management system, establishing a consistent and version-controlled foundation. A key initiative was migrating our code analysis from SonarCloud to SonarQube, deploying it via Helm on EKS and integrating it with GitHub Actions to enhance code quality and vulnerability scanning. I also enabled the Data Engineering team by deploying and configuring Airbyte and Dagster across UAT and PROD environments using Helm on EKS. To strengthen security, I implemented OAuth2 Proxy for internal application authentication and integrated AWS GuardDuty and Inspector to scan the EKS cluster and EC2 instances, taking necessary steps to mitigate identified risks and vulnerabilities. I supported and evolved our CI/CD pipeline by troubleshooting build issues in GitHub Actions and managing Docker image publication to ECR. I automated the infrastructure provisioning process by implementing GitHub Actions workflows to execute terraform plan and terraform apply commands, ensuring reliable and auditable deployments. For application deployments, we adopted a GitOps model using ArgoCD. I authored Helm charts and ArgoCD manifests for microservices, later deploying a separate ArgoCD instance for Production and migrating applications from UAT with zero downtime. To standardize deployments, I created a ge
