Computer Science Student @ NTHU

I'm an undergraduate student at National Tsing Hua University (GPA: 4.21/4.3, Top 3%) with strong interests in computer vision, AI/ML, and full-stack development. Self-driven and quick to learn — whether it's my own dev environment, architecting full-stack systems, or ML research. I turn ideas into working implementations across hackathons, research, and personal projects.
