Portfolio / Writing

Building useful products, then writing down what I learn.

I'm Justin Chung, a sophomore studying Information Management at National Taiwan University. I build products at the intersection of technology and real-world problems, with a focus on creating tools that genuinely improve everyday experiences.

I'm the creator of "不揪?", a student-focused social scheduling app that has reached over 90,000 downloads and nearly 100,000 registered users. Building and scaling it end-to-end gave me a hands-on foundation in product thinking, user growth, and full-stack execution.
