I take care of the boring parts
so other people can build interesting things.
Hi — I'm TRINH TIEN DAT, a Freelance SysAdmin, DevOps engineer, and IT Consultant. I work with businesses and individuals on infrastructure, automation, and cloud solutions.
This blog is where I share tips, tutorials, and insights from my work in the field — runbooks, opinions, lessons earned the hard way, and the occasional rant about Kubernetes. If you'd rather hire me than read about it, the services page is the shortest path. If you've already got a project in mind, say hello.
I keep a small product line on the side — ServerDeck.io and VN Guru — both built out of needs I kept hitting in client work.
Operating systems
Linux system administration — Ubuntu, Debian, RHEL, Rocky.
Cloud & bare-metal
AWS, GCP, Azure, DigitalOcean — and the occasional dusty rack.
Automation
DevOps & CI/CD pipelines, Terraform, Ansible, shell scripts.
Containers
Docker, Kubernetes, and other forms of containerization.
Consulting
Architecture reviews, second opinions, hiring help, audits.
Languages
Bash, Python, a comfortable amount of Go, just enough JavaScript.
