CTO and Developer at Group Buddies (groupbuddies.com) where I do all around web work, from server provisioning to CSS animations, but mostly interested in back end stuff with Ruby on Rails.
I've given a number of talks at conferences and local meetups on Ruby and Rails. I'm one of the founders of Minho.rb (http://www.meetup.com/Minho-rb) the local ruby meetup in the area I live.
I also have some teaching experience gained from giving multiple workshops to different audiences, and in particular due to Creators School (http://cs.groupbuddies.com/) a hands-on program for both professionals and beginners. I've also been a coach and helped organize more than one RailsGirls event, and am one of the organizers of RubyConf Portugal, the only international ruby conference in Portugal.
Apart from ruby and rails, I also consider myself to have solid knowledge of git, even though it is not really a language.
