About Jianqiang

I am a research-trained physicist turned Machine Learning Engineer, with strong foundations in mathematics, programming, and image science, and over five years of hands-on experience delivering computer vision and ML systems in startup environments.

My background allows me to bridge research and production: I am comfortable designing and training advanced models, but also turning them into robust, scalable solutions integrated into real products. I have worked end-to-end, from data definition and model experimentation to cloud-based training, performance tracking, and deployment through APIs or containerized services.

I enjoy working on applied AI problems where scientific rigor meets engineering constraints, and where machine learning creates measurable impact in real-world systems.

    June 2020 - September 2022 (2 years and 3 months)
    Paris, France
    Astartup thatprovidessolutions based on computer vision technology to industrialproducts for airport runway FOD (foreign object debris) detection.
    • • Introduced an instant segmentation model (i.e., Faster-RCNN), which reduces more than 70% system false-positive errors.
    • • Delivered a 3D-vision based module (i.e., Orthophoto), which yields better detection performance.
    • • Invented an approach to match images with different luminosity (more efficient than the state-of-the-art, e.g.,
    histogram-matching or Gamma-correction), which improves 50% of object detection rate.
    • • Designed a localization algorithm based on perspective transform, leading to an increase of the detection rate from < 10% to > 90%. Keywords: proof of concept, algorithm design, computer vision, object detection & segmentation, machine & deep learning, data analysis, computer networking.
