Technical.

Over 150 million people have used my apps. The code I write for you will be robust, fast, scalable, and secure. Whether you want a rich social-media integration that will help your product go viral, or a bulletproof data-transfer engine, I've got you covered.

Creative.

Far from just slinging code, I have a refined design sense and an in-depth knowledge of platform guidelines that builds on my creative practice. Creating a branded experience that feels 'at home' on iOS, Android or desktop isn't easy, but it's what it takes to bring users back to your app again and again.

Visionary.

But you want more than rock-solid tech. You want advice. Guidance. Wisdom. Whether you're launching a first app or a tenth, having an experienced technical voice on your strategy team can add what it takes to make sure your project delivers the value you're looking for.
