self intro for english club

Awaw self intro for English Club

Basic info

I am fumin (awaw in most places on the web) who is mainly a developer focusing on web, iOS, and Android apps. I work at cardinalblue.com. You can find more about me at github/fumin, previous homepage, and future graphics.

Motivation

To practice the English language orally, and to get to know new friends

Expectations

I hope everyone participating find the gathering interesting, helpful, and rewarding. I believe I will feel the same if everyone feels so.
