Professional Bio

I used to watch my older brother working as a developer and became interested myself. As a developer, I can deliver value and build something great to help people achieve their goals while doing what I love. My favorite technology is Ruby on Rails because it delivers a lot of value in minimal time while keeping the focus on what's most important: the product. In my free time, I enjoy playing video games.
