Hi, I am Sin Ko

I make complex products feel clear and intuitive.

Through user interviews and usability testing, I notice what users struggle with by paying attention to what they do, not just what they say.
‍
I use those insights to make complex products clear, intuitive, and trustworthy.

Product Designer focused on enterprise workflows and usability research, using AI to support my design process.
