Hi there, my name's Jiayong Ou (区家勇 in Chinese; Ou/区 is my last name), a twenty-something web developer currently working for those guys.
As you might have suspected from my name, I'm Chinese, from Shunde (map), Guangdong province. I pretty much grew up in Switzerland (and holding a Swiss passport since a few years ago). In addition to German, which I consider my native language, I speak English and Chinese. While I pretty much completely forgot how to write in Chinese, I can still speak Cantonese and a bit of Mandarin.
