Worked on the ethereum/go-ethereum repository to improve codebase maintainability by removing a deprecated vulnerability check command and its related code paths. Focused on backend development using Go, the work involved deleting obsolete files, tests, and associated JSON test data, thereby reducing the maintenance surface and aligning the project with current deprecation policies. The approach emphasized code health and long-term stability rather than introducing new user-facing features. All changes were verified through build checks to ensure no regressions. This targeted cleanup streamlines ongoing development efforts and supports the project’s commitment to maintaining a clean, policy-compliant backend codebase.
