Summary
👤
Senior🎓
Top SchoolRammus Xu is a DevOps manager with 11 years of hands-on experience architecting hybrid cloud platforms and driving CI/CD and GitOps adoption across high-scale environments. He has led cloud migrations, implemented Kubernetes (EKS/GKE) and IaC at scale, and delivered measurable savings—reducing cloud costs by 20% in three months and over a million dollars in a year using spot/on-demand strategies. Comfortable across AWS, GCP, Azure and tools like ArgoCD, Terraform, and Elastic Stack, he combines deep technical execution (Python, Go, Bash) with ISO 27001 compliance and security-conscious operations. At Binance and eslite he shortened Elasticsearch cluster launches from hours to minutes and migrated legacy jobs to Argo Workflows for scalable automation. Colleagues describe him as an automation-obsessed, organization-minded engineer who builds ChatOps and lifecycle systems that make teams faster, not just infrastructure prettier. Based in New Taipei, Taiwan, he pairs pragmatic cost-focused decisions with relentless attention to operational detail.
