Summary 7 years of experience in Software Development has driven myself to embrace Agile and Lean Thinking, applying my strong object oriented design skills in Ruby on Rails, Java, JavaScript and Python. I have about 2 years of experience working remotely in Agile projects being self-managed, proactive and keeping fluent communication with the team, always focusing on bringing clients' dreams come true. I love computers and programming since youth and I've been doing it better every new year, so I'm always reading and thinking about getting better at writing crafted and well-tested code for web applications, and also working hard to make these fulfill and benefit the properties of a real Distributed System.

The application brings up a lot of challenges like maintaining and adding features to a huge codebase with automated tests while keeping it clear and clean, coordinating integration with various external systems, complex deploy, huge database, high website load, etc. Some of the languages, frameworks, tools and techniques I've been working are: Ruby, JavaScript, Rails, Capistrano, Background Jobs, Resque, Redis, TDD, RSpec, REST, MySQL, GIT, Jenkins, Memcached, UNIX, Bash, Vim, pairing and Kanban.
