Sun, 30 Apr 2017 14:37:00 -0300https://arthursantana.github.io/about/I am a brazilian developer and entrepreneur. I dropped out of the Computer Science course at the Institute of Mathematics and Statistics of the University of São Paulo to work on my company, but I missed studying mathematics, so I came back.
