Worked on enhancing listing quality for CFA partner postings within the mission-apprentissage/labonnealternance repository by expanding the block list to filter out additional CFA school and company names from job partner listings. This backend development effort, implemented in TypeScript, focused on improving the relevance and trustworthiness of job postings for CFA-affiliated candidates and recruiters. The change was delivered as a single, well-documented commit, ensuring maintainability and traceability. No major bugs were addressed during this period, with the primary contribution centered on feature development that reduces exposure to non-partner or low-value postings, thereby strengthening the platform’s business value and user experience.
