I’ve written for (and been featured in) many magazines, newspapers and other periodicals, including The Guardian, Macworld, MacUser, The Loop Magazine, Offscreen, and more. I wrote a monthly column for every issue of Tap! magazine (December 2010 - July 2013). I’ve been interviewed, featured and quoted in various periodicals and news outlets, including The Wall Street Journal, BBC News, The Guardian, The Register, .net Magazine, and others.
I’ve written over half a million words on this site since September 2002. You can view a list of my own favourite articles. I’m currently working on a novel.
I used to be a software engineer and usability consultant - and I’m still interested in technology and software development as a hobby. My clients included Apple and other Fortune 100 companies, as well as smaller businesses and independent developers.
I’m passionate about intuitive design, multi-touch interfaces, human-focused software, and accessibility. If you are too, you might enjoy this list of my favourite books on those topics.
I’ve released a large amount of iOS and Mac source code, which has been used in hundreds (if not thousands) of apps on iOS and OS X.
I’ve also released a few apps of my own: Favorites for iPhone (speed-dial with style), Shady for Mac (dim your screen to soothe tired eyes), and Sticky Notifications for Mac (quick and easy on-screen reminders via Notification Center or Growl).
I’ve spoken at technical and design conferences worldwide, on a variety of topics including user experience, accessibility, custom UI design and implementation, and more.
