André is a highly-motivated software engineer. Ruby is his general purpose language of choice, and he writes Rails apps both professionally and for fun. He deeply believes in Agile practices and his personal motivation is pushing code to production and seeing how it makes someone's life better.

Feed Duck
Feed Duck is a gem that wraps the default RSS::Parser lib from Ruby and provides an uniform interface for reading data from Atom and RSS feeds.

Nothing But The Funk feed reader
NBTF is a feed reader app that I wrote, mostly as a design experiment. It consists of a delivery mechanism written in Sinatra and pure Ruby classes to implement behavioral specifications. Strongly enforced code boundaries for improved maintainability was the goal of this experiment.

This is still a work in progress.
