About Yohan

Expert inn8nfor 5 years, I design customn8n automationsfor freelancers, SMEs, and startups who want to eliminate repetitive tasks and integrateAIinto their **operations**.

What I automate on n8n:

→ Prospecting and Sales — automated LinkedIn prospecting systems, CRM pipelines with automatic follow-ups via Brevo, SMS, or SMTP email.
n8n automationreplaces daily copy-pasting with a continuous, monitored flow.

AI Agentsand RAG systems — I build completeRAGpipelines on **n8n**: document ingestion, intelligent chunking, Qdrant vector storage, and chatbot interfaces usable by your teams.
From raw PDF to a conversational **AI agent**, everything goes through **n8n**.

→ Internal processautomation— invoicing, PDF document generation, reporting, onboarding, synchronization between your tools (Notion, Airtable, ClickUp, Google Sheets).
Eachn8n automationis part of a global architecture, not in a silo.

→ Audit and rework — are your existingautomationscrashing or becoming unmanageable? I audit, stabilize, and rebuild onn8nwith error management, retries, monitoring, and complete documentation.

My approach to n8n automation:

I don't deliver an isolated **n8n workflow**.

Each project follows a precise framework: scoping → architecture →n8ndevelopment → testing → documentation → training.

I document eachn8n automationso your teams can take it over, modify it, and evolve it without depending on me.
