In July 2025, Benjamin Kieger enhanced the mission-apprentissage/labonnealternance repository by expanding the block list for CFA partner job listings. He focused on backend development using TypeScript, delivering a targeted update that filters additional CFA school and company names from partner postings. This change aimed to improve the relevance and trustworthiness of job listings for CFA-affiliated candidates and recruiters by reducing exposure to non-partner or low-value postings. The work was implemented as a single, well-documented commit, ensuring maintainability and traceability. While no bugs were addressed, the feature delivered clear business value and demonstrated a focused, isolated engineering approach.
