Apart of being Technical Director at XING, I help companies with improving their legacy apps. All these projects share some similar patterns: coupled code and lack of unit testing.
In this talk Carlos he'll live code, no slides. Given code from one of this projects that is written directly into the web controller with no unit testing, He'll refactor it extracting the Business Logic into Command Handlers. If we are good in time, we'll include Domain Events. Join us! It will be fun!
