Filippo Lai developed the ISBE CertAuth Helm Chart in the in2workspace/helm-charts repository, enabling scalable certificate-based authentication deployments on AWS EKS. He designed cost-optimized infrastructure using Terraform and Kubernetes, incorporating spot-based nodes, VPC and subnet configuration, and IRSA-enabled AWS Load Balancer Controller. Filippo enhanced observability by integrating Prometheus ServiceMonitor and Grafana dashboards, providing end-to-end visibility into CertAuth metrics. He automated deployment and lifecycle management with shell scripts and comprehensive YAML templates, while strengthening security through secrets management and environment-specific configurations. His work included detailed Markdown documentation, supporting cross-team collaboration and ensuring maintainable, production-ready deployment workflows for Kubernetes environments.
