Hi there 👋 I'm Jirasak (Jira)

Cloud-Native & Platform Engineer | Linux Specialist

Currently based in Osaka 🇯🇵 (Relocating to Tokyo/Chiba area soon).
I specialize in designing and implementing Hardened & Scalable Infrastructure using AWS, Kubernetes, and Infrastructure as Code (Terraform). Driven by automation, GitOps, and platform engineering principles.

🚀 Featured Projects (In Progress / WIP)

  • 🛡️ AWS-EKS-Hardened-Infrastructure - Enterprise-grade, highly secure Amazon EKS cluster deployment automated via Terraform modules. Focuses on network isolation, IAM Roles for Service Accounts (IRSA), and security hardening.
  • 🌐 iot-eks-hardened-project - Scalable cloud infrastructure optimized for high-throughput IoT data ingestion using EKS and containerized microservices.
  • 📊 aws-dataops-platform (Upcoming) - Modern DataOps platform orchestrating automated data pipelines using Prefect on top of a production-ready Kubernetes infrastructure.

🛠️ Tech Stack & Ecosystem

  • ☁️ Cloud Platform: AWS (Solutions Architect Associate), GCP
  • 🏗️ Infrastructure as Code (IaC): Terraform (Reusable Modules, State Management)
