Back to original languageAbout Julien
Intelligence is nothing without architecture. Data is nothing without meaning.
As an expert in neurosciences and a systems architect, I operate at the intersection of silicon and semantics to solve highly complex problems.
My approach merges the power of Machine Learning with the rigor of symbolic systems, ensuring explainable and hardware-optimized solutions.
I hold state certifications that allow you to transform your technological investments into tax assets: CIR/CII and approved expert by BPIFrance (Diag Data IA).
Strategic Intervention Areas
- Trustworthy AI and sovereignty: Design of RAG/GraphRAG/vectorless architectures for highly regulated sectors (Legal, Banking, Defense, Health).
- Hardware-Accelerated AI: Implementation of custom models (Verilog FPGA, RISC-V) for embedded and critical real-time applications.
- Synthetic realities generation: Simulation of behavioral data and generation of synthetic datasets for training models under GDPR / National Security constraints.
- Post-quantum cryptography and blockchain: Securing data infrastructure against future threats, certification of digital flows.
Operational Expertise
- Audit, benchmark, feasibility, and algorithmic risk analysis
- Architecture design and definition of ML/AI/Hardware innovation roadmaps.
- Hybrid modeling: complex data structuring.
- Executive acculturation: AI data diagnostics (BPI approved) and awareness of generative AI challenges for management.
Technical Expertise
- Languages and performance: Rust (Security), Go (Concurrency), Python (ML).
- Hardware: Verilog programming, FPGA architecture, and RISC-V processors.
- Data and semantics: RAG, GraphRAG, Embeddings, LLM, HRM.
- Storage space: structured (SQL), vector (Qdrant, Weaviate...), graphs (Neo4j, FalkorDB...).
