Toan Nhan developed and maintained modular cloud infrastructure components in the spartan-stratos/terraform-modules repository, focusing on scalable AWS solutions for Kubernetes, networking, and application delivery. He engineered Terraform modules for EKS, ECS, and static website hosting, integrating technologies like Helm, IAM, and CloudFront to enable secure, flexible deployments. His work included implementing KEDA-based autoscaling, EFS CSI storage integration, and advanced Route53 DNS management, addressing both operational reliability and security. Using languages such as HCL, YAML, and Bash, Toan delivered features that improved deployment automation, observability, and multi-tenant support, demonstrating depth in infrastructure as code and cloud-native DevOps practices.

April 2025 — Focused on expanding Terraform module capabilities for EKS, accelerating cloud-native app delivery with stronger storage, networking, and GitOps support. Key features delivered across spartan-stratos/terraform-modules include: EFS CSI driver integration for EKS Managed NodeGroups; Nginx Ingress Controller module for EKS; AWS Static Website wildcard domain support via CloudFront/Route53; ElastiCache Redis custom parameter groups; ArgoCD Route53 external access and in-cluster management improvements. Major bug fixes included correcting the Nginx ingress replicas variable naming and patching Argocd in-cluster naming to support multiple in-cluster configurations.

January 2025 monthly summary: Delivered key platform enhancements across Helm charts and Terraform modules that increase scalability, flexibility, and reliability for deployments. Implemented KEDA-based autoscaling across the Helm chart with new KEDA templates, enabling event-driven scale decisions. Improved Helm chart stability for multi-worker deployments and cronjobs through label deduplication and updated worker definitions, improving predictability in high-load scenarios. Introduced a KEDA module for EKS with modular IAM policy handling and separate installation paths to simplify security governance and maintenance. In Terraform modules, added AWS SES Route53 zone data integration for DKIM/MX publishing to ensure accurate DNS records, and fixed ElastiCache auth token generation gating to prevent token usage when transit_encryption is disabled. Overall, these changes increase deployment flexibility, resilience, and security posture while delivering measurable business value through faster time-to-market and reduced operational risk.
