My Heart Is in the Work.
I'm a Computer Science undergraduate at Xi'an Jiaotong University, a member of valkey-io, and a Linux kernel contributor.
I work on RDMA networking, database internals, and distributed protocols, with a particular interest in concurrency, resource lifetimes, and the behavior of systems under failure.
I speak Chinese, English, Japanese and a little German, and enjoy learning languages.
Play the long game. Do the hard, right things.
My contributions cover transport correctness, Raft cluster protocols, runtime integration, and regression testing.
| Area | Selected contributions | Merged work |
|---|---|---|
| RDMA transport | Fixed re-entrant callbacks and busy loops with IO threads, and use-after-free during concurrent client disconnects. | IO-thread integration · Disconnect handling |
| Raft cluster | Implemented pre-vote to prevent disruptive term inflation, and non-voting members with explicit promotion and demotion. | Pre-vote · Non-voting members |
| RDMA integration | Added runtime loading of RDMA libraries so CLI and benchmark tools can run without RDMA dependencies when using other transports. | libvalkey · CLI / benchmark |
| Core correctness | Fixed blocked-client use-after-free and invalid TSC calibration that could freeze the monotonic clock. | Client lifetime · Clock calibration |
| Testing & diagnostics | Added RDMA benchmark stress coverage and improved diagnostics for intermittent RDMA CI failures. | Stress tests · CI diagnostics |
Recent work on concurrency, resource lifetime management, and network protocol implementation.
