Project Experience

  1. NeuroMatrix3D: English Text to 3D Braille Model Generator
    GitHub: https://github.com/B-X-Y/NeuroMatrix3D
    Tech Stack: Python, Flask, Docker, GitHub Actions, OpenSCAD, liblouis

Independently developed a Web application that converts English text into UEB Grade 2 Braille and generates 3D models compliant with the Americans with Disabilities Act (ADA) standards, along with downloadable STL files. Built backend services using Flask and implemented containerized deployment with Docker. The project integrates accessibility technology, Web backend development, 3D model generation, and open-source engineering practices, demonstrating broad technical integration and practical value.

  1. finFlow: LLM-Based Financial News Sentiment Analysis and Visualization System
    Tech Stack: Python, Flask, Docker, Matplotlib, MySQL

Retrieves financial news links through the Yahoo Finance RSS Feed and uses ChatGPT Structured Outputs and JSON Schema to perform structured analysis of each news item’s short-, medium-, and long-term impact on specific stocks. Quantifies news impact on a 0-10 scale and generates explanations for each score. All scores and analysis results are persistently stored in MySQL. The system is deployed using Docker on Ubuntu Server without a GUI, generates data visualizations with Matplotlib, and provides Web services through Flask for online access to and presentation of the analysis results.
