À propos de Naji

I ship autonomous AI agents and RAG pipelines: from prototype to production.

At Brevo: multi-agent AI handling documentation Q&A, CRM operations, and campaign analytics. Built with LangGraph / Google ADK, served via FastAPI, deployed on Kubernetes, monitored with Langfuse. LLM-as-a-judge evaluation, human-in-the-loop workflows, and fine-tuned BERT for multilingual spam detection. Exposed the entire API as MCP servers for AI coding assistants.

Before that: led ML engineering at Forvia (predictive maintenance, manufacturing quality, time series forecasting). At Orange: applied PhD research to anomaly detection on telecom networks at scale.

PhD INSA Lyon: transformer-based unsupervised anomaly detection. Published papers (ECML-PKDD, IEEE), two international patents.



What you get:

- Autonomous AI agents (LangGraph / ADK) with tool calling and memory
- Production RAG pipelines with evaluation and quality gates
- Fine-tuned models (LoRA/QLoRA, BERT, vLLM serving)
- Deployed microservices (FastAPI, Docker, K8s)
- Full observability: Langfuse, tracing, automated checks

Stack: Python · LangGraph · Google ADK · LangChain · Langfuse · FastAPI · Docker · Kubernetes · GCP · vLLM · HuggingFace Transformers · Spark · SQL

    Senior AI Engineer
    septembre 2024 - Aujourd'hui (1 an et 9 mois)
    Paris, France
    Built and deployed a multi-agent AI assistant in production (LangChain → LangGraph → Google ADK migration), with agents for documentation Q&A, CRM management, and campaign analytics Exposed Brevo's public APIs as MCP servers (FastMCP), enabling AI coding assistants (Claude, Cursor) to use Brevo tools natively
    Implemented production-ready RAG pipelines (RagFlow, Neo4j) to retrieve information from the Brevo Knowledge Base and answer customer queries Integrated Langfuse for end-to-end tracing and automated quality checks via LLM-as-a-judge. Trained and deployed ML audience recommendation models (MLOps with ZenML and Python) to optimize targeting and maximize e commerce campaign ROI. Fine-tuned a pre-trained neural network (BERT) to detect spam and classify fraudulent email patterns. Implemented scalable API endpoints (FastAPI) to serve AI microservices (image generation for email campaigns, speech recognition for phone calls)
