Summary
I'm a Senior DevOps / DevSecOps Engineer who builds, secures, and optimizes cloud-native infrastructure on AWS, working with clients in Singapore. My core stack is EKS, Terraform, CloudFormation, and the wider AWS ecosystem. I deploy product data pipelines into client environments and take products to stable, production-ready operation. I design end-to-end CI/CD pipelines - code and container scanning with Trivy, coverage checks, builds to Amazon ECR, and deployments via ArgoCD - and automate security-critical tasks like rotating RDS passwords and IAM keys with AWS Lambda. I also remediate vulnerabilities, enforce compliance benchmarks, and optimize EKS node groups to cut infrastructure cost. Outside the core work, I love building with Claude and I'm deeply interested in agentic AI and AI-assisted development - and how they're reshaping the way we ship software. When I'm not working with code, you'll find me singing, listening to music, and playing instruments - creative outlets that keep me balanced and energized.
