Back to original languageAbout Sylvain
I help service SMEs and laboratories automate their processes and deploy AI assistants (chat & voice) to capture more leads, reduce repetitive tasks, and make their data truly actionable.
With a PhD in Materials Science and 5 years of development experience, I understand both business constraints (quality, traceability, administrative burden) and technical implementation (no-code / low-code, APIs, databases).

- Automatic lead submission to Google Calendar, CRM, email + concise weekly report.
🔹 Make Automations for Your Internal Operations
- Quick audit of your current workflows (emails, forms, CRM, files).
- Make scenarios connected to Airtable, Supabase, Notion, Google Sheets, HubSpot, etc.
- Notifications, reporting, and data synchronization without manual re-entry.
🔹 Business Mini-Apps (React + Supabase + AI)
- Mini-CRM or internal dashboard (tracking files, clients, projects, labs).
- Lightweight business tools (inventory, sample tracking, micro-SaaS).
- Smart search (RAG) in your internal PDFs, procedures, and documents.
What I bring to you:
- Dual background in lab work and development/automation.
- Focus on an MVP that delivers measurable gains within weeks.
- Clear documentation of scenarios and skill transfer to your teams.

- Déclic StratégieTransforming a Form into an Actionable AI Diagnosis and Qualified Lead GeneratorCONSULTING AND AUDITSOctober 2025 - December 2025 (2 months)Lyon, FranceDéclic AI is a web application that helps entrepreneurs, SME managers, and consultants clarify “where to start with AI”.The user answers a short questionnaire (sector, context, business priority, channel, available time) and receives an AI maturity diagnosis, 3 structured recommendations (prompt, automation, AI agent), an automation blueprint, and a 7-day action plan.The full version is delivered by email, making it both a useful tool and a powerful engine for generating highly qualified leads.Technically, I designed a modern and scalable architecture: React 18 + TypeScript frontend, Tailwind UI + shadcn, deployed on Vercel. Edge Functions handle orchestration with the OpenAI API (typed JSON responses, retry with backoff, managed timeouts, fallback engine if the API fails).Report delivery is handled by Brevo (templates + raw HTML), and each submission is properly logged in Google Sheets via a secure service account.This project demonstrates my ability to deliver a complete application combining front-end, serverless back-end, LLM integration, and automation, ready for industrialization or adaptation to other business use cases.
