Working in large open source projects, can be challenging, especially trying to keep everyone on the same page, and generating code that has enough similarities to allow shared maintenance.

The presentations covers automated QA tools as a way to make code more uniform, avoid introduction of some types of technical debt, and reduce review efforts on pull requests, while also raising the level of the review.
