We have a few case studies on this site, but unfortunately, a lot of our work is all under heavy NDA. Updated portfolio with more examples coming early April 2015.
In a private online or in-person meeting, we do show many examples of our work over the years. However, we cannot publicly post or email those flow charts, wireframes, clickable prototypes, documentation or other artifacts publicly.
For a preview of our Axure ninja skills, here are two short videos showing our Axure prototyping work. One is a full-fidelity prototype for Wells Fargo. The other is a medium-fidelity prototype with parallax scrolling and complex math calculations.
