I'm a backend engineer at Alibaba (Qwen) in Guangzhou, working on web data infrastructure — large-scale page rendering and content acquisition services that sit between the open web and LLM applications.

Day to day I write Go, Java, Node.js/TypeScript and shell, and I care about reliability, observability, and keeping systems boring.

Contributing to Kubernetes, Nacos, Redis and Prometheus. I enjoy the community side of open source and I'm interested in taking on more wherever I can be useful.

Kubernetes — currently in review:

• kubelet: mark pods NotReady on NotReady→Unknown node transition — #141550
• kubelet: defer to pod grace period when eviction-max-pod-grace-period is negative — #141551
• kube-controller-manager: contextual logging in the clustertrustbundle publisher controller — #141553
• migrate Deployment and ReplicaSet selector to declarative validation — #141558
• informer-gen: use plural-exceptions-aware namer for GVR resource name — #141566
• kubelet: add unit tests for secret manager implementations — #141567

Nacos — keeping the Node.js and Go SDKs consistent with the Java one:

• add selectOneHealthyInstance to the Node.js naming client — nacos-sdk-nodejs#152 (merged)
• align config local cache with the Java SDK (failover + snapshot lifecycle) — nacos-sdk-nodejs#154
• support publishConfigCas for optimistic-lock style config publish — nacos-sdk-nodejs#153
• always subscribe services loaded from local disk cache — nacos-sdk-go#911

Redis:

• fix keyspace notification event order for list move commands — redis/docs#3855 (merged)

Prometheus:

• procfs: model legacy TcpExt counters removed from recent kernels — procfs#863 (merged)
• node_exporter: use procfs parsers for netstat, snmp and snmp6 — node_exporter#3796 (in review)

Distributed systems, Kubernetes internals, distributed configuration and service discovery, web infrastructure, developer tooling, and open-source communities.
