Hi there πŸ‘‹ I'm Jirasak (Jira)

Cloud & Data Infrastructure Engineer

Currently based in Osaka πŸ‡―πŸ‡΅ (Relocating to Tokyo/Chiba area).
I specialize in designing and implementing Hardened & Scalable Infrastructure using AWS, Kubernetes (CKA), and Infrastructure as Code (Terraform). Driven by DevSecOps, GitOps, and Data Platform Engineering principles.


πŸš€ Featured Projects

  • πŸ›‘οΈ AWS-EKS-Hardened-Infrastructure v1.0.0 - Enterprise-grade, highly secure Amazon EKS cluster deployment automated via Terraform modules. Features 3-tier network isolation, IRSA, KMS encryption, and automated IaC security scanning (Checkov/Trivy).
  • 🌐 iot-eks-hardened-project - Scalable cloud infrastructure optimized for high-throughput IoT data ingestion using EKS, Karpenter, and containerized microservices.
  • πŸ“Š aws-dataops-platform (Active) - Modern DataOps platform orchestrating automated ELT pipelines using dlt and self-hosted Prefect Server on Kubernetes with S3-compatible storage (Floci).

πŸ› οΈ Tech Stack & Ecosystem

  • ☁️ Cloud Platform: AWS (Solutions Architect Associate), GCP
  • πŸ—οΈ Infrastructure as Code (IaC): Terraform (Reusable Modules, State Management)
  • 🐳 Container & Orchestration: Kubernetes (CKA Certified, EKS), Docker, Helm, Karpenter
  • 🐧 Core OS & Networking: Linux (Ubuntu/Debian) Server Administration (2+ Years Production Experience)
