I’m Ben Callis

Over the last ten plus years I’ve had the pleasure of working on some amazing iOS apps for some great companies. I'm currently a lead iOS developer at Waracle. A long the way I have worked a few of my own apps many of which can be found in the App Store.
Take a look at some of my work below!
