Chun-Min Chang

Hi, I am Chun-Min Chang (Kun-Bín Tiunn), a self-directed learner and a maker who enjoys building products from original ideas. As a born risk-taker with curiosity, I keep trying new things and challenging myself.

When I was child, I have dreamt about becoming a craftsman, an author, an architect, or a scientist. Now, I build products by hands as a craftsman; write quality code as an author; design software models as an architect; analyze and solve problems as a scientist.

I am a software engineer. I am living all of my dreams in my daily life.

Observe carefully. Imagine boldly.

I have been exploring the possibilities of technology to address human needs. It's as easy as an warning alarm ringing when other vehicles approach you; It's also as sophisticated as anonymous chatting (phenomena have revealed that persons who cannot date have problems when meeting face to face.) I perceive there is no boundary of my works, because the only limit is imagination itself. Parts of my projects were reported by TV, newspapers and magazines. It shows these works can really address the customer's pain points.
