Presentation Title: Making Legacy Code Your Friend

Who doesn't like to constantly work with the newest technologies, right? Who doesn't like to always work in projects with zero days of Tech Debt, no code smells, clean code and architecture and 100% of test coverage? Meanwhile, around the world, there’s much more legacy, crappy, buggy, spaghetti (call it as you wish) code created than the good one, and someone needs to maintain it. However, it doesn’t need to be painful, or a journey through hell! Let me explain to you how we deal with it here, at Vizlib, with real-world examples. This presentation will showcase best practices, basic theory, pro tips and strategies, and hopefully debunk some of the myths regarding dealing with Legacy Code. Believe it or not, the developers in my team no longer feel the difference between working on bugs or features - both have become fun, enjoyable and teachable for us. Will it be the same for you?
