Worked on the infiniflow/ragflow repository over two months, delivering features and stability improvements in Go for backend and API development. Built a reranker-based document scoring system in the DeepInfra driver and added OpenAI-compatible embeddings to the GPUStack API, expanding the platform’s capabilities. Focused on robust transport handling by hardening HTTP transport logic across multiple models, including LongCat, Voyage, ModelScope, Novita, and N1N, to prevent runtime panics with custom transports. Maintained connection pooling and timeout settings while introducing safe fallbacks, and reinforced reliability through comprehensive regression and edge-case testing, resulting in more stable production deployments and maintainable code.
