Luis de la Rosa’s Summary

I'm the founder of Happy Apps LLC. We can help you make Mac OS X and iPhone applications. We also make our own Mac and iPhone products. We use agile methodologies like Test Driven Development and specialize in Hybrid applications - those that are powered by Web Service APIs and blend seamlessly into your native desktop or mobile environment.

I'm a seasoned software veteran with over 13 years of professional software development experience. I prefer the Smalltalk family of languages: Objective-C, Ruby and Java. I am also an expert in the frameworks that help you build applications: Cocoa (for Mac applications), Cocoa Touch (for iPhone applications), and Ruby on Rails (for Web Service APIs and Web applications).
