36 years old, Brazilian/Dutch, married | |

I'm passionate software engineer who has been working most exclusively with iOS development since 2009. I find it truly fascinating that I can make people's lives better through software development and that's what motivates me to keep learning and programming. My past experiences include working on a wide range of challenging international projects for large and small companies but also engagement in building a strong developer community in Brazil and writing technical articles.
