A Cyclomatic Complexity developer analyzes software code to identify its complexity using the Cyclomatic Complexity metric. This metric, devised by Thomas J. McCabe, Sr., quantifies the number of linearly independent paths through a program's source code to assess the potential risk and testing complexity. The developer uses this to optimize code, making it easier to manage, test, and debug. They aim to reduce the complexity score, leading to higher code maintainability and readability. Their role involves refactoring code, modularizing complex routines, and ensuring good programming practices to keep the software efficient and manageable. Their work contributes significantly to software quality assurance.
