KiotViet Technology
Sep 2025 - Mar 2026 (6 months)
DevOps Engineer / SRE
Leading the modernization of legacy application platforms by migrating workloads from Docker Compose to on-prem Kubernetes. Built and operated RKE2 clusters, standardized GitOps-based delivery with ArgoCD, automated workflows with Argo Workflows, and established a full observability stack including ELK, Grafana, alerting, on-call rotation, and service-level monitoring.
- Automate everything
- Migrated legacy services from Docker Compose to Kubernetes on on-prem infrastructure.
- Built monitoring, alerting, on-call rotation, and incident response workflows for production systems.
- Defined and visualized SLI, SLO, and SLA metrics for individual services using Grafana dashboards.
- Improved platform reliability, deployment consistency, and operational scalability through automation-first practices.
