Worked on enhancing the reliability and performance of LLM integration within the Tencent/WeKnora repository, focusing on backend stability rather than new feature development. Addressed a critical issue where hung LLM calls could cause worker deadlocks by implementing robust timeout protection across both streaming and non-streaming chat entry points. Leveraged Go’s context.WithTimeout to enforce strict deadlines, coordinating these with existing caller deadlines to prevent queue saturation and ensure system resilience under upstream failures. Applied skills in API development, backend development, and concurrent programming to deliver maintainability improvements, with detailed commit documentation supporting future traceability and collaborative development within the codebase.
