CV

Software Engineer

Canon Medical Research Europe

• Responsible for the full software development life cycle of Canon Fusion, a Windows-based ultrasound fusion imaging system written in C++ (MSVC).
• Diagnose and fix software defects from customer reports; reproduce issues, debug, implement fixes, and verify by regression testing.
• Develop and extend new features such as prostate biopsy workflow, handling data, workflow logic, and algorithm integration, while also upgrading the toolchain.
• Maintain and update Jenkins CI pipeline and Gradle dependency system; manage internal modules under Mercurial (hg) version control.
• Improved domain generation algorithm with ~85% runtime reduction.
• Trained machine learning for prostate segmentation using PyTorch, including data preprocessing, cluster training, ONNX export, and Fusion integration under Git version control.
• Conduct manual and unit testing. Prepare release documentation and test logs under Agile/Jira.

Lead Engineer

Hong Kong Applied Science and Technology Research Institute Company Limited

Worked in a Diamond Classification project which:

• Designed a full optical imaging system to classify natural, synthetic (CVD), and HPHT diamonds using multiple light wavelengths.
• Built both Android (Java, C++, NDK) and Windows (C++, Qt) versions for camera control and image analysis.
• Implemented image preprocessing algorithms and trained/integrated a compact machine learning model for real-time diamond detection and classification.
• Wrote custom camera control in C++ for full exposure, gain, and trigger control (not supported by Media Foundation).

Senior Engineer

Hong Kong Applied Science and Technology Research Institute Company Limited

As the sole software and hardware engineer in my team, I developed a 3D Scanning and Spectroscopy System, which:

• Was a one-man R&D project for a structured-light 3D scanner using a single camera and three projectors (RGB, UV, NIR).
• Included the design and construction of custom control circuits to manage the entire optical system.
• Was developed fully in C# (WPF), integrating circuit control, camera calibration, 3D reconstruction algorithms, and visualization in a single software platform.
• Implemented algorithms from scratch such as structured-light phase-shift, gamma-response correction, camera calibration, and Delaunay triangulation and related geometry algorithms.
• Optimized 3D reconstruction computation by ~88% through multi-threading and pipeline refactoring.
• Built OpenGL GPU-based rendering for real-time mesh visualization in WPF.

Software Engineer

Sapiens Environmental Technology Co Limited

• Full-stack web development for IoT air pollution monitoring (Spring Boot, JavaScript, MySQL).
• Programmed STM32 MCU (FreeRTOS) for pollutant sensors; handled data storage (SD) and GPRS communication.
• Developed Python tools for sensor communication and data visualization.
