Worked on the apache/spark repository to improve code quality and maintainability by addressing a spelling inconsistency of the term 'Decommission' across both core code and associated tests. Using Scala and leveraging skills in software maintenance and testing, the developer standardized class and test names, such as MasterDecommissionSuite, to ensure consistent terminology throughout the codebase. This targeted change enhanced code searchability and reduced friction during code reviews, while also minimizing risk for future refactors. The work focused on strengthening codebase hygiene, enabling safer updates and faster onboarding for new contributors, and contributed to the overall maintainability of the project.
