Is Your Code Becoming Unmaintainable?
As software projects grow, code quality often deteriorates without regular refactoring. Technical debt accumulates, making changes more difficult and increasing the risk of bugs. Refactoring is not just a cleanup activity—it’s a critical practice that should be integrated into your daily development workflow to ensure long-term project success.
