About Hichem

Deploying an AI system in 2026 involves simultaneously managing four risks that most POCs overlook:
  • Exposure of sensitive data to the LLM,
  • Dependence on a single vendor (hyperscaler or model),
  • Lack of traceability of decisions for AI Act audit purposes,
  • Uncontrolled inference costs at scale.

It is on these four axes that I have structured my interventions for 9 years, on Data/AI projects in production.

The method is consistent:
  • Agents in LangGraph
  • Vector RAG with NER anonymization upstream of the LLM
  • Orchestrated multi-agents
  • Hosted on Scaleway and/or any other French or European provider depending on the context
  • LangSmith or LangFuse for traceability
  • Token budgets for cost control
  • Model fallback for continuity
  • Queryable decision log for compliance

Context: I have co-managed DPLIANCE since 2019, a publisher of sovereign Data & AI solutions based in Poitiers. The studio publishes Mirage Analytics, Complio, and Cookilio, and delivers tailor-made AI solutions hosted in Europe. Our GDPR compliance software is used by several hundred organizations in France.

Recent references:
  • Winner of the ADEME 2024 Data/AI Challenge — autonomous agent connected to the SIRENE API to verify eligibility for public aid.
  • As part of an international team, we won a major account tender for a €70M PoC (communication exclusively in English).
  • Visiting lecturer in AI, AI Cybersecurity, and MLOps at Engineering Schools and Universities (ESIGELEC, IUT La Rochelle).

Three intervention formats:
  • AI Act risk audit for an AI system in production.
  • Design and production deployment of an agentic system from A to Z.
  • Fractional Chief AI Officer to frame an AI strategy.

Excellent freelancer!! A mastery of his subject, and expertise that he enjoys sharing on ML, which I really needed. The work is clean and communication is great. Deadlines slipped a bit, but that's an inherent problem with tech solutions, involving back-and-forth. You have to be flexible!! I will work with Hichem again whenever I can. Thank you very much for your services.
