programming, user experience, and more

About the Blog

My name is Andrew Wagner and I am a software developer focussed on iOS and web development. I have a passion for product and user experience development. I don't care what technologies or skills I have to learn as long as they allow me to shape the products I develop to provide the best experience possible for its users.

My main skills are in programming and user experience, but I have dabbled in graphic design, product design, marketing, business development, and everything else involved in turning an idea into a marketable reality.

On this blog I write about the practical things that I come across while working as a freelance developer and building my own app business.
