AI Engineer — Gen AI Developer / Multi-agent Systems
I design and deploy end-to-end generative AI systems: orchestrated multi-agent architectures, specialized RAG pipelines, persistent memory, and agentic workflows in production. I handle everything from architectural design to cloud deployment, focusing on reliability, cost control, and industrialization.
Types of missions I am looking for
- Gen AI Systems Architecture : multi-agent design, model routing, context/memory layers (episodic, semantic), autonomy gradient
- Vertical RAG Pipelines : specialized corpus ingestion and structuring, vector databases, chunking and retrieval strategies, relevance evaluation
- Prompt Engineering : structured system prompts, prompt chaining, function calling, constraints, and guardrails
- Agentic Workflows : agent orchestration, tool use, synchronous and asynchronous processing, event-driven
Tech Stack & Domains
- Models : Claude (Haiku, Sonnet, Opus), GPT, open-source models; multi-model routing based on cost/quality
- Frameworks : Claude Agent SDK, managed agent services, MCP
- Cloud : AWS, GCP, Azure — managed agent and knowledge base services, serverless functions, NoSQL databases, event bus
- Reference Architectures : multi-agent, RAG, persistent memory, function calling
My Contribution
- Systems Thinking : I design complete architectures, not just isolated prompts or API calls
- Industrialization : my systems are designed for production — reliability, controlled costs, managed latency, observability
- Verticalization : I structure areas of expertise into knowledge layers usable by agents
If you are building a Gen AI product and looking for someone to handle end-to-end architecture, I would be happy to discuss it.

- LEXGUILDAI Engineer — Gen AI Systems, Multi-agents & Legal Knowledge BaseTECHApril 2026 - Today (2 months)Paris, France
LEXGUILD — Specialized Multi-Agent System for Legal Education (SaaS / EdTech / LegalTech)
Context & Objective
Design, architecture, and deployment of a multi-agent system for law students in France (L1, L2, L3).LexGuild acts as a cognitive orchestration layer: a multi-agent system that understands the student's progress, selects the right exercise at the right time, mobilizes the correct texts and case law via specialized RAG, and delivers measurable progress towards academic success.Detailed Missions
System Architecture & Design- Design of a multi-agent architecture orchestrated on AWS Bedrock (relation, context, knowledge, orchestration, trust, workflow, output layers)
- Design of a model router to optimize cost/quality ratio per educational task type
- Design of the pedagogical knowledge graph: student profile, episodic memory, multi-axis methodological calibration, longitudinal progress curve
AI Production & Automation- Design of specialized multi-agent workflows (tutorials, methodology, assignment grading, revision, mock exams)
- Structuring of system prompts per agent and per pedagogical modality
- Industrialization of Lambda Action Groups (StudentProfiler, MemoryExtractor, ProgressTracker)
- Implementation of the legal RAG pipeline: Bedrock Knowledge Bases indexing codes, case law, and doctrine with domain-specific granularity
Cloud Infrastructure & Data- Full-AWS architecture: Bedrock (models + Knowledge Bases + Agents), Lambda (orchestration), DynamoDB (profiles, episodic memory, sessions), EventBridge (asynchronous processing)
- DynamoDB table design
- Design of session lifecycle Lambdas
