This was a weekend project to help protesters in Brazil to vote on causes they think are most important to move Brazil forward. It was built using Meteor.js (Node.js + MongoDB), jQuery, and Twitter Bootstrap.
uMotion
A market web app that implements a search retargeting technique. It is based on an existing system in Java, but is reimplemented from scratch in Grails.
It includes functionality to batch import client data from different datasources by means of a configurable parser using JSON, XML, or CSV.
It's currently in production for some big clients that generate a lot of traffic.
The app is very new and is deployed for a client, so there isn't a link to it.
