During June 2026, work on the tekdi/user-microservice repository centered on implementing audit logging for the Center Management Batch Management module using TypeScript, NestJS, and backend development best practices. The approach involved introducing audit logging scaffolding to enhance traceability and accountability of user actions, followed by a controlled rollback to maintain system stability and prevent integration issues. All changes were meticulously documented with explicit commit messages for traceability. This disciplined process demonstrated a strong focus on change control, ensuring that new features were validated for impact and that any reversions left the module stable and free of unintended side effects.
