Ruby on Rails Developer

I have been involved in the Web development and Open Source for about twelve years. Most of that time working with PHP but I moved to Ruby after I tried it for the first time. I love doing clean code and using the best practices on each project I am involved. I enjoy trying new tools and technologies and I am always looking for the best approach to solve the problems. I spend many of the free time learning new languages, frameworks or technologies by my self, looking for the best alternatives for the projects I’m working on. When I’m not programming, I like running, swimming and from time to time, a little of mountain bike. Watch movies; go to the theater and the beach.
