Smaller teams require larger efforts. Whether you're testing a concept or to rapidly shipping new functionality or messaging, a designer that knows the nuts and bolts of shipping code can help you accelerate your development significantly. And shipping faster means learning faster, iterating faster, improving faster and succeeding faster.

Your competition's designer probably can't do that. And if they can, then yours certainly should.

HTML, CSS, Javascript

From marketing pages to web apps, with frameworks or without, having a knowledge of the elements of web development enable me to rapidly test product concepts or marketing efforts and to ship product and website updates faster than if I were simply delivering mockups. With the advent of responsive web design, creating mockups is also no longer an effective way to design websites or communicate responsive behavior.

C#, XAML, .NET

While specialized software developers may be faster at developing the back-end, I bring an attention to detail that only a designer can offer for the front-end. As a designer, I've found that personally developing UI for WPF Windows applications is a sure way to vastly accelerate the velocity of any Windows desktop development team.
