Hi, I'm Ray.

I'm a 4th-year Computer Science student at National Cheng Kung University (NCKU). Over summer 2026 I was a research intern at the Institute of Information Science, Academia Sinica, and I'm continuing that work on LoRA adapter reuse as a part-time research assistant. I started building AI learning tools by accident — experimenting with side project ideas, I tried combining AI with something I actually cared about: learning Japanese. That experiment stuck, and the work since has felt purposeful in a way that's hard to manufacture. Being a learner myself means I can judge my own tools critically and solve the pain points I actually hit.

This site is my public build journal. It's where I document what I'm building, share what I'm learning, and think through the design decisions along the way. You'll find polished essays alongside rough build logs and quick notes — all part of building in the open.
