DevOps Engineer
I build infrastructure that's reproducible, observable, and safe to change — then write down how it works, so the next person doesn't have to reverse-engineer it.
I'm a DevOps engineer in Ho Chi Minh City, Vietnam. I started out on on-premises systems and moved into cloud platforms (AWS, Azure) — which left me with a habit of not trusting anything I can't tear down and rebuild from scratch.
Most of my public work is documentation-first: the Kubernetes and Terraform references I wanted to exist, AWS study notes from my own certification prep, and toolkits that collapse a checklist of local installs into a single `docker pull`. TheDevOpsHub grew out of wanting all of it in one place.
This site is one of those projects too — a build-time GitHub data pipeline feeding a statically exported page, so there's no server to babysit and the project list below can't quietly drift out of date.
Open to DevOps roles, open-source collaboration, and genuinely interesting infrastructure problems. Email is best for anything substantial — the rest work fine for a quick hello.
A central DevOps learning space
Documentation, hands-on samples, and demos for a wide range of DevOps tools and clouds, built up one practical repository at a time.
I build and maintain TheDevOpsHub myself — most of the curated projects below started as material for it. The goal is a single place to point people (including future me) at working examples instead of scattered notes.
Across the projects curated on this page, refreshed daily from GitHub.
The tools I reach for day to day. Counts show how many of the projects below use each one.
The ones I'd point at first — the projects people actually clone, star, and come back to.
A practical, docs-first reference for the DevOps toolchain: CI/CD, containers, IaC, and monitoring, organized for day-to-day lookup rather than tutorial reading.
1.8k+ stars, the most-referenced entry point into the collection
A curated set of AWS service notes and learning resources, structured around the topics that come up most when studying for AWS certifications.
Aligned with AWS Solutions Architect Associate exam topics
A single container image bundling Ansible, Terraform, kubectl, Helm, and the AWS/Azure CLIs, so a DevOps environment is one `docker pull` away instead of a local install checklist.
Security-first base image, published to Docker Hub
Everything curated in one place. Filter by category, language, or topic to find the relevant one.

Security-first base image, published to Docker Hub
A set of self-contained DevOps projects covering AWS, Azure, containers, and CI/CD, built to practice putting individual tools together into something that resembles real infrastructure.
Hands-on exercises for building DevOps muscle memory -- short, focused tasks rather than long-form tutorials.
Terraform code for common AWS lab scenarios, written to be read and modified rather than run as a black box.
Kubernetes deployment samples and practices collected from real troubleshooting sessions, kept runnable rather than purely illustrative.
A small tool that generates an overview of a GitHub account's repository landscape -- the seed idea behind this portfolio's own project grid.
A running bookmark of shell commands reached for often enough to be worth not re-Googling every time.
A curated list of GitHub Actions workflows worth stealing, organized by what they automate rather than by popularity.
Filters for finding approachable open-source issues to contribute to, built after one too many dead-end searches through mislabeled backlogs.
A running list of tools worth keeping around, added whenever something earns a permanent spot in the toolbox.
A small collection of Dockerfiles for common DevOps tools, written to be copied into other projects rather than used as-is.
A Terraform project laid out around module structure and state management conventions worth reusing on new infrastructure.
Working examples of Azure DevOps pipelines, kept around as a reference for YAML syntax that's easy to forget between projects.
A containerized local development environment supporting multiple languages (Python, Go, JavaScript), so switching project stacks doesn't mean reinstalling toolchains on the host machine.
Demo Terraform code for an AWS CodePipeline setup, kept as a reference for wiring pipeline stages without re-deriving the Terraform resource graph each time.
Share of curated projects by primary language — mostly infrastructure code and the shell glue around it.
