I like fixing things and am passionate about using new technologies to solve problems. I find the process of learning by fixing/solving problems rewarding.

In summer of 2014, I built a Chrome app "PttChrome" by utilizing open source code from author of BBSFox, PttChrome is essentially a Chrome port of BBSFox with more user-friendly features added.

As of summer of 2017, PttChrome has 314k weekly users.
