Freelancer profile translated to English.
Back to original languageAbout Guillaume
I help companies build AI systems that truly run in production: agents, business copilots, automations, and data pipelines.
10 years in data & machine learning. Developed and launched two AI products with paying clients in under 6 months.
WHAT I DEVELOP
— AI Agents & Business Copilots: Designing LLM agents capable of analyzing, deciding, and acting (Claude API, RAG, Qdrant):
— Process Automation: Connecting your tools and automating your workflows without code for the business side (n8n)
— AI APIs and Backends: Clean, tested, production-deployable architecture (FastAPI, Python, Railway, Docker)
— Data Pipelines & ETL: Reliable data that powers your AI systems (dbt, SQL, Pandas)
CONCRETE USE CASES
— Document Assistant: Your teams query your internal docs in natural language, with real-time sourced answers
— Analysis Copilot: Automated business diagnostics, scenario simulation, actionable recommendations
— Automation Agent: Email triage, reporting, document processing with human validation in the loop
— AI Content Generation Engine: Automatic delivery after payment (Stripe, Resend, Vercel)
WHY MY PROFILE IS DIFFERENT
Before Generative AI: 10 years of data — predictive scoring in banking, industrial ETL, decision-making dashboards for Société Générale, Ipsos, Ministry of the Interior.
I don't build demos. I build systems grounded in real data and business constraints.
Concrete example: AI parenting assistant deployed on WhatsApp — multi-agent architecture, persistent memory per family, automated 21-day onboarding, integrated Stripe monetization. Active users from launch.
