About Me

I started out with a BS in Mechanical Engineering, but once I began to code I was hooked! I love the combination of creative and technical problem solving that coding provides.

Originally from Brazil, I've backpacked through 30+ countries, lived on 3 different continents, and speak 2 languages. When I'm not programming I enjoy producing electronic music and DJ'ing.
