DataVisor · Infrastructure EngineerDataVisor · 基础设施工程师DataVisor sells fraud detection as a service, mostly to banks and payment providers. I'm on a four-person SRE team that owns the company's whole infrastructure layer: 50 self-managed Kubernetes clusters, 6 AWS regions, 600+ nodes, and I'm primary on-call for it. Work there includes the fleet upgrade from 1.24 to 1.29, the move from ClickHouse to Doris with compute–storage separation, per-tenant alerting, and a triage agent wired into production alerts.DataVisor 以 SaaS 形式做反欺诈，客户主要是银行和支付机构。我在四人 SRE 团队负责全公司的基础设施层：50 个自建 K8s 集群、6 个 AWS region、600+ 节点，兼 primary on-call。做过的事包括集群从 1.24 升到 1.29、ClickHouse 迁到 Doris 存算分离、租户级告警，以及接入生产告警的排障 agent。

Intel · Cloud Software EngineerIntel · 云软件开发工程师5G vRAN cloud-ification: moving the radio access network off purpose-built hardware onto general-purpose servers. I wrote Go microservices and Kubernetes operators; the main project was a declarative config daemon on 300+ bare-metal nodes that held kernel and hardware baselines to a declared spec and recovered across reboots. It's also where I learned observability from the ground up: Prometheus federation, Loki, Jaeger, OpenTelemetry.5G vRAN 云化：把无线接入网从专用硬件搬到通用服务器上。我写 Go 微服务和 K8s operator，主项目是一个跑在 300+ 裸机节点上的声明式配置 daemon，把内核和硬件基线收敛到声明的状态，跨重启也能恢复。可观测性也是在这里从头学的：Prometheus 联邦、Loki、Jaeger、OpenTelemetry。
