Along with building apps consider using best known practices to show you can go from concept to delivery including using mockups for GUIs, Gherkin (cucumber/specflow) for features and stories, a backlog manager for the mockups and features (pivotaltracker is ok for this but there are others: check them out), use a repository of some kind (I like git), setup a continual integration server, stick your solutions on a cloud service (http://aws.amazon.com/free/, Heroku is free too).
Read about Customer Development (The Four Steps to the Epiphany by Steven Gary Blank) or I am sure there are other approaches (this one just makes sense to me).
