Developed and delivered the ISBE CertAuth Helm Chart in the in2workspace/helm-charts repository, enabling scalable certificate-based authentication deployment on AWS EKS. Focused on cost optimization and observability, the work included Helm templates for Kubernetes resources, deployment automation with shell scripts, and Terraform-managed infrastructure such as spot-based nodes, VPC design, and IRSA-enabled load balancers. Enhanced monitoring was achieved through Prometheus ServiceMonitor and Grafana dashboards, while security was strengthened with secrets management and environment-specific configurations. Comprehensive Markdown documentation guided installation and usage, supporting cross-team collaboration and operational hardening. The project emphasized maintainability, automation, and visibility for Kubernetes-based authentication solutions.
