Software engineer based in Hangzhou, China.

I work on backend systems, developer tooling, and Go SDK/CLI reliability.

My recent open-source work is focused on Lark/Feishu developer infrastructure: auth correctness, token cache safety, WebSocket lifecycle bugs, streaming downloads, cross-platform CLI behavior, and automation-friendly error handling.

• Go backend engineering and platform tooling
• Lark/Feishu SDK and CLI reliability
• Auth, token lifecycle, cache isolation, and transport edge cases
• WebSocket concurrency, graceful shutdown, and streaming I/O
• Structured errors and test coverage from both RD and QA perspectives

I prefer practical fixes to tools that developers actually run: reproduce the issue, isolate the root cause, add regression coverage, and keep the change small enough to review.

Merged Lark/Feishu contributions:

• larksuite/cli#1454 - clarified remote event bus recovery when local status / stop cannot fix a remote blocker. Merged.
• larksuite/cli#740 - migrated task shortcut failures from bare errors to structured CLI errors for machine-readable recovery. Merged.

Active Lark/Feishu work under review:

• larksuite/oapi-sdk-go#218 - isolates app and tenant token cache entries by app secret fingerprint to avoid credential cross-use.
• larksuite/oapi-sdk-go#217 - adds streaming Drive download APIs to avoid buffering large files into memory.
• larksuite/oapi-sdk-go#215 - guards WebSocket client config updates to remove a data race.
• larksuite/oapi-sdk-go#216 - adds graceful shutdown support for WebSocket clients.
• larksuite/cli#1525 - fixes Windows exec provider security audit false positives caused by synthetic Unix mode bits.
• larksuite/cli#1524 - translates rich text segment styles in Sheets cell writes.
