I use Apple hardware and Mac OS X since the age of dawn but work doing Android and iOS development these days. Used to be a .NET/C# guy back in the early 2000s.
I did some Objective-C for Mac a very long time ago, but now I merely ready Obj-C if I need to, for I didn't even have ARC when I used it. Instead I use Swift on iOS, which I love; but I'm not an expert with it (far from it).
I have lived in the sunny Spain near Madrid for over eleven years, but now I live in San Francisco, CA.
