Description

I help companies design and integrate useful, reliable, and connected generative AI solutions with their existing tools.

I mainly focus on LLM, RAG, AI agents, business automation, and backend integration: internal assistants, intelligent documentation search, information extraction, document analysis, request qualification, structured content generation, AI-augmented workflows, or business tools connected to models like OpenAI, Mistral, Anthropic, or open-source models.

My approach is pragmatic: start with a real business problem, prototype quickly, measure the value, and then industrialize properly when the solution brings concrete gains.

My experience in senior backend development: APIs, microservices, databases, processing queues, security, observability, Docker/Kubernetes, distributed systems, allows me to go beyond a simple AI demo and build maintainable, monitored, secure solutions integrated into a real environment.

Example missions:

Create an AI assistant connected to your internal data;
Implement a reliable RAG with cited sources;
Automate the analysis of documents, emails, tickets, or reports;
Design AI agents capable of calling your APIs or business tools;
Evaluate the benefit of fine-tuning or an open-source approach;
Transform an AI prototype into a usable backend application.

I work with CTOs, product teams, business managers, or founders who want to move from "we should do something with AI" to a concrete, useful, and sustainable tool.

January 2025 - Today (1 year and 7 months)
Paris, France
Design and development of an AI Lab environment dedicated to experimentation, orchestration, and integration of AI agents into development and analysis workflows.

The project aims to transform advanced AI uses into concrete tools: specialized assistants, task-oriented agents, prompt generation and review, code auditing, document analysis, workflow automation, and interaction with existing technical environments.

Work performed:

Design of an orchestration architecture for LLM agents;
Creation of multi-agent workflows with specialized roles: implementer, reviewer, auditor, analysis assistant;
Integration with development environments, project files, tickets, and backend tools;
Structuring operational prompts to produce, audit, or validate technical deliverables;
Experimentation with RAG, contextual analysis, and the use of local or remote models;
Implementation of controlled flows to track decisions, validations, and outputs produced by agents;
Work on the reliability, traceability, and industrialization of AI uses beyond simple prototyping.

This experience combines generative AI, LLM agents, business automation, and backend expertise to create truly usable AI tools in a professional context.
