About TechD

Robin Hsu, and where the name TechD comes from

I'm Robin Hsu, an iOS engineer. TechD is my one-person app studio, which I jokingly call my one-man independent brigade. Most apps here started as something I needed myself: notes for a game, a way to sort a collection, a tool to test BLE devices. Once one works well enough for me, I polish it and put it on the App Store, hoping it helps someone with the same need.

"TechD" isn't an existing word. It's the first letters of the BBS handles of five close friends from my university days: T, e, c, h, D, and I'm the e (ender). Later I got into One Piece and loved the "D." in the middle of its characters' names, so I started writing myself as Tech.D.Robin Hsu. A bunch of overgrown teenagers thought it looked cool, and the name has stuck ever since. The Chinese name is a pun rooted deep in the Taiwanese soul: 鐵克豬, which sounds like "TechD" and ends with the character for "pig."

If the apps bring in a little income, it gives me more room to keep these tools maintained.
