Software development for Mac OS X, iOS and Java
I have been developing software for Apple Macintosh forever, since the year the Mac was born. And, also since it's been available, I've extended that to iOS (iPad, iPhone, iPod touch). For developing web and server applications, I'm a long-time user of Java and related technologies (like Grails).
I have built Mac, iOS and Java applications for many customers for in-house and commercial use. I can also call on the assistence of other professional developers and designers on larger projects or when additional expertise is required.
Developer training
What I do is what I teach. You can build upon my extensive experience with developing software for Mac OS X, iOS and Java by following a course.
I teach Java courses for Sun/Oracle; the Mac OS X and iOS development courses are my own creations.
Products for iOS
The Apple App Store is my friend. As well as developing iOS applications for my clients, I have also published my own iPad app: Memorazzo.
