It's a little difficult to start writing a vouch for Clauber, because he has done so many amazing contributions to Mozilla that you can easily get lost. He was one of my "mentors" on the community in a time we were small and starting to build Mozilla Brasil as it is today. He built add-ons, organized events, made lots of documentation and internacionalization... The list goes on and on. He is a great friend, an amazing person and one of the key members of our community.
