Senior🎓
Top SchoolMango Yen is a Senior DevOps Engineer with 11 years of experience building secure, observable, and automated cloud-native platforms across finance, advertising, and semiconductor industries. He has led large-scale observability rollouts (OpenTelemetry, Prometheus, Grafana) and optimized alerting and metric ingestion for high-volume environments, including coordinating AMP quotas with AWS. A strong security-minded practitioner, he designs fine-grained IAM, implements Vault-backed secret management, and automates CIS-aligned hardening and hardened AMI builds via Packer and Ansible. He accelerates delivery through Terraform, ArgoCD, Jenkins, and GitHub Actions, and has a track record of improving developer efficiency with reusable CI/CD and testing templates. At Cathay United Bank he combined cloud observability with an LLM-driven RAG pipeline to automate internal document summarization—demonstrating a blend of SRE skills and emerging AI tooling. Based in Taiwan with a Master’s in Computer Science from National Chiao Tung University, he prefers solving hard operational problems pragmatically rather than labels.
