    AI / Backend Engineer, RAG Pipelines

    Saifly · United States (Remote)

    • Took a compliance RAG pipeline from a zero baseline to recall@k 0.448 and MRR 0.382, using Docling chunking, pgvector retrieval, and an eval harness that tracked recall, precision, MRR, and NDCG.
    • Built semantic chunking with clause-level embeddings and token-boundary limits, plus metadata-rich indexing so retrieval could actually be explained.
    • Cut ingestion overhead with async batching, dedup, and incremental re-indexing.
