About me

I'm a DevOps Engineer based in Hanoi, currently working at Sava Meta. My focus is on Configuration Management, SCM, Build/Release Management, and Infrastructure as Code.

I bridge the gap between application teams and infrastructure — having shipped production code myself, I understand what developers need from a platform: fast feedback loops, reliable CI, clear logs, and tooling that doesn't get in their way.

I've shipped CI/CD pipelines with Jenkins, GitHub Actions, GitLab CI, and ArgoCD; built monitoring stacks with Prometheus, Grafana, ELK, and OpenTelemetry; and managed Kubernetes clusters on AWS for both internal AI platforms and Web3 trading systems.
