If this term gives you shivers, you know it can cause harm to your product. Legacy code uses outdated technologies and practices, making it harder to maintain the project and get new professionals to work on it. As a consequence, it can significantly decrease the speed of developing new features. Unfortunately, it's not easy to get rid of it, as re-writing code with new technologies also takes a lot of time, making it really hard to convince the stakeholders. In this talk, we'll see how we managed to get rid of legacy code at Westwing, sell the idea to our stakeholders, and introduce modern technologies to the codebase. ## Speaker ### [Christian Souza Valentin](https://www.wearedevelopers.com/@christian-souza-valentin) Senior Software Engineer at Westwing ## Related talks at this congress - [Grappling With Clunky Old Software?
