I am from Salvador/Bahia, and I write code. In fact, I think that software development is the best contruction toy ever invented.
Software currently drives a very large part of our lives in society, and it is very important that the society, and not only software vendors, have control over that software. Having control of software means having control over what is done with your personal data and with the information you produce. Because of that, I believe that free software is the only ethical way of producing and distributing software. In some cases (but not always), free software is also the most effective way of developing software.
I’m a founding partner and software developer at Colivre.
