Worked on the ovh/manager repository to enhance the backup agent framework by introducing a customizable query client and refactoring data fetching logic. Leveraging React, React Query, and TypeScript, the developer consolidated data management for baremetal and vault resources, enabling the use of query hooks to streamline and standardize data retrieval. This approach improved the testability and maintainability of the backup agent, allowing for more flexible and reliable testing utilities. By focusing on API integration and front end development, the changes reduced flaky tests and made production rollouts more predictable, ultimately strengthening the reliability and validation process for backup operations.
