During February 2025, Bastien Montois focused on backend reliability for the Max-Eee/E-commerce-recommender repository, addressing two critical bugs using TypeScript and his expertise in API integration and cache management. He implemented an authentication-aware guard to prevent Customer API calls when no JWT is present, reducing unnecessary traffic and improving security. Bastien also corrected signout cache invalidation by replacing an unused static cache tag with a dynamic customer-specific tag, ensuring accurate data consistency after signout. While no new features were shipped, his targeted fixes enhanced system stability, lowered error rates, and maintained reliable customer data flows throughout the authentication lifecycle.
