I spent a long time trying to fix a legacy product that kept slowing our team down. Every small update turned into a chain of side effects and temporary patches. What helped was stepping back and getting an external technical audit and rebuild plan. I found a useful breakdown of modernization approaches on a site that explains how to move from unstable architecture to something maintainable without freezing delivery. The key idea was iterative refactoring with business goals tied to each sprint. After applying that mindset, releases stopped feeling risky and started feeling controlled. It is not magic, just disciplined engineering and clear priorities.
