Description

AI Developer & Integrator, I help freelancers and SMEs design and deploy custom AI solutions: AI agents (RAG with knowledge base), chatbots, generative AI tools, and process automations. I handle everything from audit/ideation to production, with an approach focused on reliability, performance, and adoption.

Areas of Expertise:

AI Agents & RAG Chatbots: Assistants connected to your documents (Notion/Drive/PDF/CRM), semantic search, business logic, reliable answers with sources/citations (LangChain, Pinecone, or equivalents).
SaaS & Web Apps: Development of modern, scalable applications (Next.js, React, Tailwind CSS) integrating AI features.
Prompt Engineering & System Design: Structuring prompts, tools, guardrails, testing, and iteration for stable production results.
LLMs & Orchestration: Integration of models (GPT, Claude, Llama, etc.) and setup of RAG/agent pipelines (RAG + strict rules + third-party tools).
Automations & Integrations: Workflows and API connections (emails, CRM, support, billing, calendar...), eliminating manual tasks.
Data & Extraction: Document parsing, classification, information extraction, and actionable insights.

Services:

Quick POC / MVP: Validating a use case with measurable results.
Full Production Solution: Design, development, deployment, and monitoring (logs, response quality, continuous improvement).
Maintenance & Optimization: Knowledge base enrichment, error reduction, evolution.

Why work with me?

I build useful and robust AI solutions, designed to function in real-world conditions: integrated with your tools, focused on time savings, with a strong emphasis on reliability (sources, rules, guardrails, human validation if necessary).

I create custom AI solutions for freelancers and SMEs: from RAG AI agents connected to a knowledge base (documents, processes, internal tools) to a complete infrastructure integrating AI, designed for your use cases (AI SaaS, business web app, dashboards, etc.).

The solutions developed are typically chatbots and AI agents for customer or internal support, RAG systems for intelligent document search and utilization with sources, AI workflows for sorting and qualifying information (emails, tickets, business data), as well as AI dashboards and tools for management, reporting, and decision support.

Each solution is custom-designed to fit your business and generate concrete time savings, with a focus on ease of use and production reliability.

It's difficult to give a very positive review, it might seem excessive, but I must say that the work and collaboration with Mathieu suited and satisfied me perfectly. Mathieu is very intelligent in understanding the project as a whole and in its details. And there's no need to explain at length for him to program concrete, creative features or details, even beyond my expectations. And all this very quickly, moreover, reachable almost 7/7 and from morning to late evening. In short, excellent work and I wish to continue long-term with Mathieu. I recommend him 100%, you can even contact me to verify this recommendation.
