I am focused on building reliable cloud and DevOps systems: Kubernetes clusters, GitOps delivery, infrastructure automation, reverse proxies, monitoring, and practical production operations.
name: Nguyen Quang Canh
handle: croyce97
role: Cloud / DevOps Engineer
focus:
- Kubernetes platform engineering
- GitOps delivery with Argo CD
- Infrastructure as Code with Terraform
- Observability with Prometheus and Grafana
- Linux, networking, reverse proxy, CI/CD
mindset:
- simple architecture
- clear runbooks
- secure defaults
- fast rollback
- production-first troubleshooting
| Area | Practical work |
|---|---|
| Kubernetes | Cluster bootstrap, workloads, ingress, probes, resources, autoscaling, rollout and rollback |
| GitOps | Argo CD applications, App of Apps, sync policy, environment promotion, drift control |
| Cloud infrastructure | Terraform modules, AWS networking, EC2/EKS-style labs, SSM-first access patterns |
| Observability | Prometheus, Grafana, Alertmanager, uptime checks, Kubernetes dashboards |
| Delivery | Docker image pipeline, CI/CD quality gates, Helm-based deployment, release safety |
| Operations | Linux debugging, networking, NGINX/HAProxy, incident notes, runbooks |
| Lab | Goal |
|---|---|
| Kubernetes on EC2 | Build an on-prem style Kubernetes cluster with kubeadm, containerd, Calico, and SSM access |
| GitOps observability | Manage Prometheus, Grafana, ingress, certificates, DNS, and Rancher through Argo CD |
| Production Kubernetes notes | Turn course material into reusable commands, manifests, checklists, and interview-ready notes |
| Financial platform DevOps | Design Kubernetes, CI/CD, observability, and security patterns for regulated systems |
- Prefer simple systems that are easy to operate under pressure.
- Automate repeatable work, but keep the failure mode understandable.
- Treat observability, rollback, and security as part of delivery, not afterthoughts.
- Write documentation that helps another engineer recover the system at 2 AM.
