Hey, I'm Colin 👋

Tsinghua PyPI

Undergraduate student currently learning AI and reinforcement learning, with an interest in reasoning and agent systems. I enjoy turning ideas and personal needs into working software.

What I'm Building

Smart Calendar Assistant

A personal Google Calendar assistant built for my own study workflow. It understands my class schedule and routines, turns natural-language requests into calendar actions, and helps me review how I spend my time.

JavaScript Google Calendar API LLM Integration

AI Finance Analyzer

An experimental Python package exploring how rules, statistical analysis, and LLMs can turn expense records into practical suggestions.
