Over the past six years, I've designed and maintained production Kubernetes clusters, automated CI/CD pipelines, and built cloud infrastructure that companies actually rely on. My work keeps applications running smoothly while dev teams ship faster. ## What I've actually done: - I've migrated legacy CI/CD systems to modern Kubernetes-native workflows, reducing deployment times and eliminating manual bottlenecks. - Built production EKS and AKS clusters from scratch using Terraform, complete with monitoring, security hardening, and disaster recovery. Designed and implemented GitOps workflows with ArgoCD that let teams deploy confidently without breaking production. - For one client, I rebuilt their entire data platform infrastructure—MinIO, Spark, Airflow, dbt, the works—all running on Kubernetes with full automation. - Another project had me maintaining Azure network infrastructure across multiple regions while supporting developer teams who just needed things to work. ## My availability: I'm based in Ho Chi Minh City and work during business hours that overlap well with US and European time zones. I'm a Certified Kubernetes Administrator and comfortable working with teams of any size, from startups to established companies. ## What I can help you with: - Setting up production-grade Kubernetes clusters (EKS, AKS) with proper security, monitoring, and backup - Building CI/CD pipelines that actually work—GitHub Actions, ArgoCD, Jenkins, Argo Workflows - Infrastructure as Code with Terraform—from VPCs to complete environments - Migrating legacy systems to cloud-native architectures - Troubleshooting deployment issues and fixing infrastructure problems - Setting up observability stacks (Prometheus, Grafana, OpenSearch) I respond quickly, explain technical concepts clearly, and don't disappear once a project starts. If you need someone who's dealt with production infrastructure in the real world and can get things done without drama, let's talk.

I help engineering teams stabilize infrastructure and streamline deployments using AWS, Terraform, and Kubernetes. Most clients retain me long term after initial setup to manage CI/CD pipelines, backend reliability, and production operations. With over 7+ years of hands-on DevOps experience, I work directly on Terraform provisioning, container orchestration (ECS/EKS), GitHub Actions and Jenkins pipelines, and AWS-native automation. My focus is building infrastructure that is secure, observable, and ready for continuous delivery. My focus is building infrastructure that is reliable, secure, and easy for development teams to deploy into whether supporting a SaaS platform, internal systems, or data-intensive applications. If you are facing unstable deployments, unclear infrastructure ownership, or slow release cycles, I can audit your current setup and implement practical, measurable improvements.

Hello World, You are seeing a DevOps Engineer profile. I graduated from the University of Information Technology (Vietnam National University HCMC). I have a good base knowledge of Networking and Telecommunications. DevOps is my passion so I decided to change my career path from DotNet Software Engineer to DevOps Engineer. Currently, I'm working on a project related to mobile testing. I'm responsible for building, managing and scaling CI/CD system. In my project, I have done such things: - Implement CI (Continuous Integration) system using Jenkins especially Jenkins Pipeline. - Replace Jenkins with Travis CI because Jenkins becomes unstable and needs to self- managed nodes. - Setup, configure and manage IT infrastructure automatically by Ansible. - Implement CD (Continuous Deployment) system using Rundeck. - Work with AWS (Route 53, EC2, S3, RDS, ECS, EKS) for building the entire application ecosystem. - Work with Elastic Stack (Elasticsearch, Logstash, Kibana) for application log management. - Write custom rules for alerting critical messages within five minutes or normal messages within twelve hours from Elasticsearch. - Setup and configure Elastic APM to monitor application performance. - Work with Docker (dockerize applications, build applications from docker images). - Build API documentation by using Swagger and user documentation by using Slate. - Setup and configure reverse proxy Nginx to handle requests for ensuring the availability, scalability, confidentiality. - Work with mono-repo to centralize repositories and manage dependencies easily. - Setup and configure Metabase to analyze the company’s data. - Code scripting languages such as Bash, Python. I know that I'm just a drop in the bucket but I will do the best things to make everything gets better and stronger.
