SUMMARY
I'm a Senior Software Engineer with deep skills in Ruby ecosystem, Java and Javascript. I have a rich
experience on modern development frameworks, such as Rails and Sinatra.
API design, software architecture and CI excites me.
Although being a Ruby expert, I really enjoy playing with different programming paradigms such as
Functional Programming on JVM based languages. I'm currently learning Clojure and have contributed
to Project Euler (solving complex math problems through programming), for instance. Self-learner.
My Github is full of side projects, including general available opensource code, gem libs and college
contributions. Be my guest!
