What I Do

I advise and develop solutions, with a particular focus on media technologies for Mac OS X (QuickTime, QTKit, Core Audio, etc.), and iPhone (Core Audio, H.264 playback, iPod access, GameKit, image capture and rendering). Previously, I worked extensively in cross-platform Java applications and applets (QuickTime for Java [QTJ], Java Media Framework [JMF], Java Bindings for Open GL [JOGL], and JavaSound).

Currently, iPhone is my primary focus. Aside from co-writing the book, I'm writing articles for the Apple Developer Connection on iPhone development on topics such as UIKit, networking, and Core Audio. I'm also developing new applications for sale on the App Store. Below is a collection of screenshots from various projects I've created (click for full-size image):

Previous projects for Mac and Java have included:

• proof-of-concept apps for server-side movie construction in memory and totally with media references (as opposed to disk/memory copies), supporting track-level segment editing
• development of an on-screen preview component for QuickTime for Java video capture, blitting pixel data from QuickDraw to Java2D, and accounting for live device and configuration changes
• a capture-and-go application (Mac, Windows) for recording and editing personal video messages
• server-side transcoding of audio files into a cell-phone friendly format
• development of a Java Swing GUI for monitoring traffic on a media distribution network
• development of an open-source, cross-platform MP3 http-streaming (ie, "shoutcast"-like) client library, with metadata tag parsing
• development of a Java wrapper around the Objective-C QTKit framework

I also have the expertise to write about and train developers in cross-platform media development, with real world experience of what works and what doesn't. I also produce podcasts and edit video, which gives me an affinity to clients' professional media needs.
