Worked on the opensearch-api-specification repository to address a critical stability and security concern by resolving an integer overflow vulnerability in the DocStatus metric. The solution involved upgrading HTTP status code counts from int32 to int64 within the YAML schema, ensuring accurate tracking of high-volume status codes and reducing the risk of overflow in production environments. Updated both the _common.yaml schema and the project’s documentation to reflect these changes, maintaining clear traceability and alignment with project standards. Focused on API design and schema definition, the work prioritized data integrity and reliability without introducing new features during the development period.
