Infrastructure & DevOps leader specializing in multi-cloud, Kubernetes, and AI infrastructure delivery.
ChinaWhat I'm looking for
I am an Infrastructure and DevOps leader with 20+ years of experience building and operating large-scale, reliable systems across multi-cloud and on-prem environments. I have led teams of 30+ engineers and delivered overseas system rollouts and active-active datacenter builds.
My strengths include multi-cloud architecture (Alibaba Cloud, Huawei Cloud, AWS, GCP), Kubernetes container platforms, and DevOps pipelines that dramatically improve deployment speed and system availability. I have implemented CI/CD (Jenkins, GitLab), observability stacks (Prometheus, Grafana, ELK), and robust monitoring to reduce MTTR and incident rates.
I have driven significant cost optimization and compliance work, including reducing annual IT spend at OneConnect from ¥80M to ¥50M and supporting regulatory audits. I focus on operational excellence, high availability, and secure global infrastructure management.
More recently, I have concentrated on AI infrastructure and enterprise-grade LLM application platforms, deploying RAGFlow, Langfuse, and RDAgent, and building cross-cloud private networks to unify global operations.
