Email · Apache Dubbo · Open-source contributions
I build infrastructure for systems that need to stay understandable under pressure—whether the traffic comes from services or AI agents.
I'm Yukina, an Apache Dubbo PMC member and Java open-source contributor based in China. My work sits at the intersection of distributed systems, service governance, and agent infrastructure.
- Distributed systems — RPC, protocol design, service governance, reliability, and security in Apache Dubbo.
- Agent infrastructure — production-grade Java agents, A2A interoperability, and MCP integration.
- Open source — maintaining projects, reviewing changes, shipping releases, and turning edge cases into durable fixes.
| Project | What I work on |
|---|---|
| apache/dubbo | PMC member; maintaining the Java RPC and microservice framework across transport, governance, security, agent integration, and releases. |
| agentscope-ai/agentscope-java | Contributor; improving long-running agent reliability, A2A behavior, runtime isolation, and safety. |
| a2aproject/a2a-java | Contributor to the official Java SDK for the Agent2Agent protocol. |

When I'm not debugging distributed systems, I'm probably in a CS2 match. I'm also open to thoughtful opportunities with strong engineering and a healthy work-life balance (WLB).
