Lin Manhui

Over six months, Minghao Lin enhanced document understanding and OCR capabilities across PaddleOCR, CherryHQ/cherry-studio, and PaddlePaddle/PaddleX. Lin delivered new inference modules for layout, table, and formula recognition in paddlepaddle/paddleocr, optimized CPU inference with MKL-DNN, and integrated benchmarking utilities for performance evaluation. He improved deployment reliability by restructuring dependency management, refining CLI tools, and updating packaging processes using Python and TOML. Lin also expanded multilingual support, streamlined onboarding with clearer documentation, and enabled PaddleOCR integration in coze-studio and cherry-studio. His work demonstrated depth in backend development, API integration, and dependency governance, resulting in more robust, maintainable systems.
