JINYAO (Timmy) LU

Software engineer with experience working on Linux-based systems and embedded-related projects, using C/C++, and Python. Experienced in firmware validation, FFmpeg media pipelines, and system-level debugging across Linux, Android, and Windows platforms. Successfully integrated computer vision and OCR solutions into industrial workflows, enhancing production-level accuracy through effective model training and system optimization.

Industrial Chemical Diagram OCR System 

• Built an OCR pipeline for industrial chemical process diagrams to handle practical issues such as rotated text, dense symbols, and low-contrast annotations.
• Integrated PaddleOCR, Google OCR, and a custom preprocessing workflow (rotation correction, region segmentation, noise filtering) to improve baseline recognition quality.
• Performed targeted model fine-tuning on domain-specific diagram datasets, significantly enhancing recognition robustness for rotated and skewed text.
• Achieved around 95% character-level accuracy on angle-standardized chemical diagrams, validated across multiple diagram formats and layouts.

Operating System Development Project (C)

• Implemented core OS components including memory allocation, thread scheduling, synchronization primitives, and process management, gaining deep understanding of low-level system behavior.

C/C++ Programming Project 

• Built multiple applications (e.g., Tetris, Snake) using X Window System, emphasizing modular design and low-level event handling.
• Developed a MIPS compiler in C, covering lexical analysis, parsing, intermediate representation, and code generation.
