    Mac OS X Applications Developer

    United States - Last active: 03/04/2014

    I've been working with Macintosh systems professionally since 1987. Though my position has often been "Systems Administrator," a lot of what I do involves writing code. When I can't find an off-the-shelf Macintosh software solution, I'll write my own. I've been using Xcode, creating applications and utilities in Objective-C & Cocoa for the last couple of years; writing utilities and applications in AppleScript Studio, pure AppleScript; and writing shell scripts in Bash and Perl. My applications are typically single-window utilities, built with a single purpose in mind. I do take care to ensure the UI in my utilities behave properly. Interface elements are only enabled when they can be used, progress indicators are only visible when necessary, buttons and text fields resize intelligently with the window. I take pride in my work, and I know a developer is never finished learning. I'm a firm believer in commenting my code, and do so profusely. Here begins the adventure!
