Mobile App Developer

We are looking for someone who can build a VERY basic app that we have designed. We are also looking for a developer that can develop an app that is compatible with iOS, Android, and the web with a single codebase so as to minimize needing to develop 2 separate apps.

Please follow the instructions below:

1) In the subject, type: “App Development Job Application - Scoreboard”
2) Please put a link to one of the apps you have developed
3) If you have a portfolio please also include that link
4) What platform/programming language do you use for app development?
5) Why do you prefer that programming language?
