Due Diligence RAG System
Design and development of a RAG (Retrieval-Augmented Generation) system for automated analysis of large document corpora (data rooms, financial reports, legal contracts) for M&A due diligence operations.Implemented Architecture
- Multi-format ingestion pipeline (PDF, DOCX, XLSX, images) with OCR, semantic chunking, and structured metadata extraction
- Hybrid indexing on LlamaIndex Cloud / LightRAG combining dense vector search and knowledge graph for entity resolution and multi-hop reasoning
- Citation enforcement ensuring traceability of each response to its sources (page, paragraph, original document)
- Hallucination detection through post-generation verification (NLI, RAGAS metrics) and cite-or-abstain policy
- Agentic orchestration for complex queries requiring decomposition and cross-document synthesis
Deliverables
Fully functional product delivered as a ready-to-deploy Docker Compose stack, detailed technical architecture, volume scenarios (indexing, inference, storage costs), and integration documentation.Stack:Python, FastAPI, LlamaIndex Cloud, LightRAG, PostgreSQL (pgvector), Neo4j, Redis, LLMs & embeddings, OCR, Docker Compose.Keywords:RAG, due diligence, knowledge graph, GraphRAG, hallucination detection, source traceability, LLM, generative AI, NLP, multimodal document processing. - Multiples clientsSenior IT Consultant: AI/ML, Neurotech, Full-Stack & SecurityDecember 1999 - Today (26 years and 5 months)Over 25 years of freelance experience, covering a wide range of IT disciplines, for clients ranging from large institutions to startups and research labs.AI & Machine Learning —Data engineering, supervised/unsupervised/reinforcement learning, deep learning, time series, knowledge graphs, embeddings, vector search, RAG, LLM integration and finetuning, agentic AI, evaluation, guardrails.

- TimefluxNeuroscience EngineerBIOTECHJanuary 2017 - Today (9 years and 5 months)I am the author ofTimeflux**, an open-source framework in **Pythonfor real-time acquisition and processing of biosignals, published in the proceedings of the 8th International BCI Conference, Graz, 2019. Designing and maintaining such a project requires cross-disciplinary expertise: modularsoftware architecture(execution graphs, plugin system),low-latency asynchronous programming**, **hardware integration(EEG, ECG, EDA, eye-tracking drivers),real-time protocols(LSL, ZeroMQ, OSC),applied neuroscience(BCI paradigms, EEG neurophysiology),signal processing(SciPy, Pandas, Xarray),machine learning(scikit-learn, Riemannian geometry), design ofuser interfaces(web, stimulus presentation), and community management for anopen-sourceproject.Timeflux is used in production by neurotechnologycompanieslike Inclusive Brains, Conscious Labs, and Open Mind Innovation, as well as by internationalresearch institutionssuch as the French Institute of Aeronautics and Space (ISAE-SUPAERO), Lund University (BCI-HIL framework), Tampere University, and GIPSA-lab.The framework has enabled several results **surpassing the state-of-the-art**. In 2022, the ASAP pipeline, based on Bayesian accumulation of Riemannian probabilities, significantly outperformed standard P300 classification methods on public datasets. In 2024, the StAR paradigm improved cVEP accuracy from 65.6% to 96.3% with 88s of calibration, and reached 97.5% online on an 8-electrode dry EEG, paving the way for usable BCIs outside the lab.I have also given over 50 talks and workshops on these topics, in both academic and industrial settings.
