Work History

Computer Vision Engineer Intern

Huidao Technology

03.2025 - 05.2025

Developed and deployed a YOLOv5-based vision system to detect, classify, and count warehouse items from live camera feeds, enabling accurate stock valuation for bank credit assessments.
Solved camera distortion and off-plane misalignment issues, achieving 60% improvement in counting accuracy.
Optimized inference pipeline by exporting models to ONNX/OpenVINO and deploying in a Dockerized GPU server, reducing latency and improving scalability.
Streamlined startup by automating environment initialization, cutting system configuration time by 50%.
Enhanced aluminum bar recognition project for precise detection and measurement, integrating automated pricing logic.

Junior Software Engineer (Intern), Technical Development Department

Zhengzhou Times Tower Graphic Design CO., Ltd

07.2024 - 10.2024

Internship Project: Developed a Python-based animation tool for creating simple 2D animations of geometric shapes, allowing users to input basic parameters (shape type, size, color, movement path) to generate replayable short animations. Implemented a user-friendly GUI using Tkinter and utilized the Matplotlib library for rendering animations.
Gained experience with Unreal Engine 5 and Unity, assisting senior developers in virtual simulation projects; Learned to implement basic Pixel Streaming protocols in Unity, enabling real-time rendering of architectural visualizations; Acquired foundational skills in 3D modeling using 3ds Max, creating simple objects and applying basic textures to support virtual environment development.
Participated in bug fixing and code review processes; Collaborated with senior developers to refactor a 5000-line codebase, improving its readability and maintainability; Contributed to the development of internal coding standards documentation, focusing on Python and C# best practices for graphics programming.
