Rémi Melisson contributed to SocialGouv’s code-du-travail-numerique and srdt repositories by engineering robust search and data processing features over five months. He developed unified search result retrieval, ensuring consistent user experience across interfaces, and migrated search infrastructure to Elasticsearch for improved data integrity and scalability. His work included implementing NER-based anonymization using spaCy, enhancing legal data ingestion pipelines, and integrating hybrid retrieval systems that combine BM25 and dense methods for better search relevance. Using Python, TypeScript, and React, Rémi focused on backend and frontend development, data engineering, and API integration, delivering maintainable solutions that improved reliability and search accuracy.
January 2026 monthly summary for SocialGouv/code-du-travail-numerique. Key deliverable: Unified Search Result Data Across Interfaces. This feature unifies data retrieval so the presearch modal results align with the actual search results, providing a single source of truth and consistent user experience across search interfaces. Commit 03ba96f9d935bee96d3f3d6721cb33aef7dae656 (feat(search): use same results for presearch modal and actual search (#7061)) with co-authors Rémi Melisson and maxgfr. Impact: improves UX reliability, reduces ambiguity, and facilitates future maintenance. No major bug fixes reported this month. Technologies demonstrated: search data unification, cross-interface consistency, collaborative development, and disciplined version control.

December 2025 monthly summary for SocialGouv development teams. Delivered cross-repo improvements across cdtn-admin, code-du-travail-numerique, and srdt, focusing on data accuracy, search performance, and scalable architecture. Key outcomes include enhancing the Employment Law entity recognition dataset, introducing a dynamic search pathway with expanded presearch capabilities, applying presearch token exclusion to reduce noise, and migrating to Elasticsearch for robust data handling and improved data integrity. These efforts resulted in faster, more accurate search experiences for users and strengthened data pipelines for long-term maintainability.
