I'm Dave; I'm a husband, a father, and a software engineer for [Apple](http://apple.com). I have a degree in [Computer Science](http://cs.byu.edu), and occasionally contribute on [StackOverflow.com](http://stackoverflow.com). I am extremely opinionated about [parsing mathematical expressions](https://github.com/davedelong/DDMathParser) and how to properly manipulate dates programmatically. Bowties are cool.
