DevOps / Infrastructure Engineer with 5+ years of hands-on experience across Linux systems, networking, virtualization, containerization and cloud infrastructure (AWS, GCP). Proven track record designing and operating production Kubernetes and Docker Swarm platforms for high-traffic international gaming systems serving up to 100,000 concurrent users. Skilled in CI/CD automation, monitoring and observability (Prometheus, Grafana, ELK/Loki), and cost-conscious infrastructure design.

Currently expanding programming and automation tooling skills to strengthen infrastructure-as-code and DevOps automation capabilities.

DevOps Engineer at Elofun Entertainment LLC (2022-04 – Present)

• Designed and operated Docker Swarm infrastructure for a high-traffic production game system serving ~100,000 concurrent users, integrating third-party CDN (Cloudflare / Akamai) to optimize global content delivery.
• Designed and operated a production Kubernetes platform as the centralized backend for core systems, managing not only application services but also database orchestration, replication, disaster recovery and scheduled backups.
• Implemented Horizontal Pod Autoscaler (HPA) and Kubernetes CronJobs to dynamically scale workloads and automate operational tasks; deployed Ingress-NGINX and Cert-Manager for traffic routing and automated SSL/TLS management.
• Containerized and deployed game services on AWS ECS with Fargate; configured VPC networking, ALB, ECR and IAM for a production game platform (Hai Tac Loan Dau: Idle AFK).
• Containerized services with Docker and managed Kubernetes deployments via Helm for a production game system (~10,000 concurrent users); designed configurable, multi-environment Helm charts, reducing manual deployment errors.
• Automated dev/UAT environment provisioning so developers could deploy and test features independently and quickly.
• Built monitoring and alerting with Prometheus, Grafana, Loki and the ELK Stack across Docker and Kubernetes environments.
• Managed Proxmox VE virtualization infrastructure, including live VM migration and online backups with zero downtime.
• Evaluated infrastructure architecture choices (Docker vs. Kubernetes) based on scalability, operational complexity and cost, avoiding unnecessary orchestration overhead on stable, resource-constrained workloads.
