Atol CD / AMeXio Group

  • Optimized the RAG pipeline for Chatcoop, an AI chatbot for agricultural cooperatives — hybrid reranking (cosine similarity + IDF-weighted keyword scoring) lifted retrieval from outside the top 5 to #1.
  • Benchmarked 250 queries across query rewriting, segmentation, and reranking strategies, documented as a reproducible methodology.
  • Built an end-to-end document pipeline: PyMuPDF, Mistral OCR, smart segmentation, mistral-embed vectorization, PostgreSQL/pgvector indexing.
  • Designed query classification to detect business cases, extract metadata, and dynamically size context windows.
