For Sebastian Serrano's work at WeGIF
I met Sebastian at the first Startup Weekend Buenos Aires in 2011. We were both team members of the winner team. Later, I outsourced some stuff with him through his firm "DevsAr". He delivered what I asked for on time, with great quality. Sebastian is a great developer and is a very trustable person. I totally recommend Sebastian.
