- Python developer
- March ― June 2013
I developed a Python web application, deployed on Google App Engine, in a team comprised of 4 Python developers, a mathematician and a neuroscientist, using the Scrum agile methodology. Because the project was complex, I insisted we all agreed on a common vocabulary. I made decisions with the end-user in mind, improving the ideas of some features, prioritizing them and sometimes, choosing not to implement a misfeature. I refactored agressively, didn't let technical debt accumulate and demanded we formatted the code according to PEP-8 because readability was very important. I made architectural decisions, but never alone, sharing that responsibility with the great programmers on the team.

- C#/.net library for receiving and understanding e-mail messages and their parts. Its greatest advantage is being completely object-oriented, in the sense that the tree of MIME parts is represented by polymorphic classes which contain data and behaviour. This allows it to represent any e-mail message with any configuration of attachments.
