Software Engineer @ PicPay

Dad, husband, woodworking hobbyist, skater noob and Software Engineer that loves to organize the fridge. Currently, work as Staff Software Engineer at PicPay on Platform iOS. My first contact with programming was in the early 2000s, creating scripts for the IRC Clients. Since then, I have never stopped programming. I started my career working with Backend and Frontend and then I migrated to Mobile about 6 years ago. I'm an enthusiast of the software craftsmanship movement, I love creativity, and I always look for an alternative to everything.

Feb 2013 – Apr 2015

I worked as a web, iOS, and macOS developer programming in Ruby on Rails, Swift, and Coffee Script. Was a great opportunity to use MongoDB. The most curious project was a solution similar to a social network but for horse owners. And the most challenging, mostly because of the MongoDB usage and macOS apps development, the intention was to measure teams productivity based on machine usages.
