About Me

I moved from Taiwan to the US in 2019 and began my coding journey at UCSD in 2022. I thrive on solving complex problems and am currently interning at Ubitus, where I develop MCP tools for the company's LLM - UbiGPT. I've also contributed to robotics demonstrations in Taiwan's largest AI exhibition - AI WAVE. In my free time, I enjoy developing personal projects, playing badminton, and exploring the latest in tech.
