Romain Melisson contributed to the SocialGouv/srdt repository by building and enhancing search, data ingestion, and privacy workflows over a three-month period. He developed an IDCC integration with dedicated API endpoints, leveraging Python and TypeScript to enable environment-based feature toggles and improve search relevance. Romain replaced LLM-based anonymization with a spaCy-powered NER workflow, strengthening data privacy for legal documents. He also implemented a hybrid retrieval system combining BM25 and dense methods, refactored APIs for content retrieval by ID, and improved ingestion reliability through robust JSON parsing. His work demonstrated depth in backend development, information retrieval, and natural language processing.

Month: 2025-07 — Focused on strengthening data privacy workflows and expanding data ingestion capabilities for SocialGouv/srdt. Key features delivered include an NER-based anonymization workflow using a French spaCy model to replace personal information with standardized tags (replacing previous LLM-based anonymization) and a JSON parsing path for Code du Travail data to ingest and analyze code du travail. These changes enhance privacy, data quality, and analytics capabilities, with robustness improvements in the ingestion pipeline.

June 2025 performance snapshot for SocialGouv/srdt: Delivered IDCC Integration and Search/Reranking, enabling IDCC data source, pyarrow-based data handling, and dedicated API endpoints for searches and reranking. Implemented environment-based feature toggles to control rollout across development, pre-production, and production, along with model/config adjustments to improve ranking relevance. This work enhances discoverability of collective agreements and delivers more relevant results while maintaining safe, incremental rollout.
