Hi, I'm Kai 👋

M.S. Computer Science @ Northeastern University (Silicon Valley) | B.S. Information Security @ Fudan University

I'm a graduate student focused on machine learning, computer vision, and full-stack development. Currently looking for 2026 Summer SWE / ML internships.

🔧 Tech Stack

Languages: Python, Go, C/C++, Java, JavaScript, TypeScript, Dart

ML / CV: PyTorch, TensorFlow, OpenCV, YOLO, DeepFace, Tree-sitter

Backend: FastAPI, Flask, gRPC, REST APIs, WebSocket

Frontend: Flutter, React, PyQt6

Tools: Docker, Git, Linux, GDB, QEMU

📌 Featured Projects

Pedestrian Attribute Detection Pipeline

End-to-end CV pipeline integrating TOPICTrack, UPAR, and YOLOFaceV2 for pedestrian detection, tracking, and attribute analysis. Fine-tuned 400M-parameter backbone, achieving 98% detection accuracy.

AI Life Planning Assistant

Multi-agent trip planner (Scout → Simulator → Validator) powered by Google Gemini API. Built with Flutter frontend and FastAPI backend with real-time WebSocket alerts.

TypeScript Static Analyzer

TypeScript parser and control flow analyzer built on the LIAN framework. Transforms TypeScript AST into Glang IR and constructs control flow graphs for static analysis.
