Porto Alegre, Brazil
I am an ex-physician, have studied mechanical engineering for a while, and have a master degree in product design.
Now I work designing diagnostic equipment (surface EMG, posturography, pedobarography), dealing with system requirements, data visualization, and GUI design, and the like.
I am also a die-hard cyclist, be it trails (not much nowadays), off-road, commuting, touring or randonneuring. Besides, I have deep interests in bike design and mechanics.
