About Laurent

Do your teams spend hours manually processing content, answering the same questions, or navigating tools that don't communicate with each other?

I integrate AI directly into your existing products and processes: no disposable POCs, just production code.

My typical interventions:
– Adding an AI assistant to a SaaS dashboard (support, input assistance, intelligent search).
– Automatic summarization of long content (job offers, product sheets, internal documents) directly within the interface.
– Automatic text generation (emails, marketing content, product descriptions) from business data.
– Custom internal tools: mini-analytics, reporting, back-office task automation.

Stack:
– Frontend: React.js, Next.js, React Native
– Backend: Node.js, Express, GraphQL
– AI: OpenAI (GPT, RAG), internal assistants, text processing & summarization
– DB/API: PostgreSQL, MongoDB, Supabase, Prisma
– CI/CD & hosting: GitHub Actions, Vercel, AWS, DigitalOcean

Based in Bordeaux.

📩 I offer a free AI audit (30 min video call + Notion summary) to quickly identify what can be automated or boosted by AI in your existing application.

Laurent created the website for my law firm. He took the time to understand my expectations. The communication was very smooth and responsive. And above all, I am very happy with the result, I have a very beautiful website, to my taste, and I have already received positive feedback from people who consult it. It's certain that if I need other IT services, I will use Laurent again. Thank you :)
