About William

I transform OpenClaw (the most powerful open-source AI agent of the moment) into your 24/7 digital employee.

Senior AI Engineer & DevOps (ex-Médiamétrie, MyMoneyBank, ADEO), I combine my expertise in AI Agents (LangChain, RAG, AWS Bedrock) and automation (n8n, production pipelines) to create highly effective OpenClaw agents perfectly tailored to your business.

What I do for you:
- Agent that automatically responds on WhatsApp, Instagram, Telegram, email
- Lead qualification + appointment scheduling in your calendar
- Customer follow-ups, quote tracking, Google reviews management
- E-commerce automation (Shopify, Amazon, Cdiscount)
- Intelligent daily reports + data scraping
- Everything integrated with your existing tools (Gmail, Calendly, Notion, etc.)

Simple installation + video training included
You save 8 to 15 hours per week without coding
