Worked on the apache/atlas repository to enhance backend robustness by addressing a critical bug in type-definition creation. Focused on Java-based API development, the work introduced centralized validation logic to prevent the use of reserved keywords as type names, thereby reducing runtime errors such as ClassCastExceptions. By implementing a dedicated error code and a helper function for name validation, the changes improved error handling and ensured that invalid type names are rejected early in the workflow. This targeted update strengthened the reliability of type-definition management, reflecting a methodical approach to backend development and error prevention within the project’s core logic.
