In addition to feature work, maintained repository health through non-functional housekeeping commits, emphasizing codebase hygiene and consistent commit history. Demonstrated attention to maintainability and traceability, supporting future development by adhering to project conventions and ensuring that documentation and repository standards remained up to date.
