Who Is S&F?

Chris Adamson, President and "Director of Code and Media", has been developing software professionally since 1997, focusing on client-side GUI development and media-distribution technologies. He is the co-author of iOS SDK Development (with Bill Dudney) and Learning Core Audio (with Kevin Avila), along with the catalog titles Swing Hacks (with Josh Marinacci) and QuickTime for Java: A Developer's Notebook.

What I Do

I advise and develop solutions, with a particular focus on media technologies for Mac OS X and iOS (AV Foundation, Core Audio, Core Video, Core Image, etc.). Thanks to a wide variety of client engagements, I'm broadly experienced in most of the iOS APIs.

Previous client projects include:

• Motivational calendar / goal-tracking iOS app, based on best-selling self-help product line
• OS X video production application to apply real-time chroma key effect, off-line crop/scale/drag and export
• Bluetooth iPhone application for monitoring/controlling proprietary automatic-transmission bicycle
• Digital "course-pack" iPad article reader for higher education, supporting highlighting (and import/export of highlight files) in EPUB/xhtml and PDF
• Web radio client with real-time iPod EQ effects applied, regardless of source format (MP3, AAC, Ogg, WMA, etc.)
• Social "challenge" game with push notification
• Effects / audio "sweetening" chain for OS X CD burning application
• OS X daemons and agents for user-monitoring application, along with custom installer
• Maintenance / new features in iPhone app tied to cable/satellite broadcaster's live coverage of major 2011 sporting event

I've also had several of my own apps on the iOS App Store over the years. I'm also actively developing my skills for livestreaming by setting up a personal livestreaming site on AWS and developing private Roku channels with that platform's public SDK.

I frequently speak at developer conferences, including CocoaConf, Voices That Matter, and MobiDevDay. Previously, I was the Editor (for O'Reilly Media) of the industry-leading developer community java.net and of ONJava.com. Prior to switching to the computer industry in 1997, I was a Writer / Associate Producer at CNN Headline News.

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 video livestreams, which gives me an affinity to clients' professional media needs.
