Worked on the coveo/platform-client repository, focusing on backend and API development using TypeScript. Addressed a critical bug in the Permission Filter API by adding a missing organization parameter and correcting the getPermissionFilterTargets function signature, ensuring API calls were properly structured for accurate data retrieval. Prioritized stabilizing core API interactions over new feature development, with the goal of improving data accuracy and reliability for downstream consumers. Validated the fix through code reviews and lightweight testing to minimize regression risk and maintain integration stability. Demonstrated attention to detail and a methodical approach to backend problem-solving within a TypeScript codebase.
