I work with both backend (Web services, RESTful services, database communication) development and frontend (web technologies such as: HTML, CSS, Javascript, jQuery, Backbone.js and Require.js; Flex, WPF).
With a BS in Computer Science and almost 9 years of experience in development, I've already worked in front-end and back-end, with several different languages, platforms, frameworks and technologies in general. I've worked with: PHP, C++, C#, Java, Scala, JavaScript, to name a few languages. I like to consider myself a generalist. I'm motivated and I like to learn new things.
