ABOUT ME

Senior iOS Developer with experience since 2009

Senior iOS Developer with industry experience since 2009. I have worked on dozens of mobile applications and continue to strive for quality in everything I create.

I help companies create quality products in the beginning, or turn their already created application into one, that will last the test of time so it doesn’t need to be completely rewritten in a few months. Unlike other developers, I have experience from initial idea, to design, through implementation, and deployment, so I can predict potential problems before they happen to reduce costs.

A little more about me, I’ve launched several dozen complex iOS apps. Collectively, they have grown to many millions of active users. My clients include Apple, Time Warner Cable, DaVita, Experian, Charter Communications, and many more. Check below for just a few of the apps I have worked on!

A completely contactless payment application that integrates directly into a client's point-of-sales system to facilitate location based services. For example, a customer can walk into a restaurant and sit down. The system recognizes the arrives at the restaurant and starts a tab in the restaurant's PoS. The customer just says their name, and orders what ever they want. The customer can then leave anytime they want and the system will pay their bill automatically.
