At VNPAY, I implement, operate, and upgrade Kubernetes and OpenShift clusters on vSphere for production and UAT environments. I build GitLab CI/CD pipelines with Vault-based secret management and manage customized Helm chart deployments.

I've also operated bare-metal cloud-storage infrastructure at FPT Telecom and maintained Linux-based SMS Marketing services at VIVAS. My work spans Prometheus, Grafana, centralized logging, Bash, NGINX, Tomcat, Redis, HAProxy, virtualization, high availability, and load balancing.
