I am known as *dema* in the Rails community.

Started using Ruby on Rails in my computer science masters degree thesis on semantic web technologies, combining ActiveRecord and the ActionPack with RDF and Sesame.

I work as the chief software architect at "Interface TI":http://www.interface-ti.com.br, a start-up born within one of the most prestigious computer science universities in Brazil, "PUC-Rio":http://www.puc-rio.br 

We are a small and aggressive team that builds great web software products. In the past five years we've been using Microsoft technology, mostly the .NET Framework and the C# language.

Lately, we prefer to use Ruby on Rails as it gives us superpowers and allows our team to build better, faster and cheaper web-based software.
