What's the difference

Over the last 14 years I have developed a wide range of applications for desktop, web and embedded systems in small, medium and large Brazilian companys using Java, Microsoft .NET, C, Ruby, Rails, Groovy, Python, Windows XP Embedded and Linux Embedded. Now I'm looking for new experiences with remote working in application development.
