Hi n8n community,
I’m Abdelrahman, an AI Automation Engineer specializing in n8n workflow
orchestration and production-grade WhatsApp AI systems.
Core stack (production-tested):
- n8n workflow automation + multi-stage orchestration
- RAG pipelines — Supabase pgvector + semantic search
- WhatsApp Business Cloud API integration
- OpenAI (GPT-4o-mini) — vision, extraction, classification, agent logic
- Redis (session/state management), PostgreSQL, AWS S3
- Docker deployment on self-hosted VPS (production, not demos)
Past work:
Built and currently maintain an end-to-end invoice automation system for
a Dutch logistics company — WhatsApp message comes in, an AI agent
matches the client against a database via RAG, validates the data,
generates the invoice, and replies automatically. Currently handling
300+ invoices and roughly €150K+ in value with zero manual entry. Also
built a WhatsApp-based appointment booking/scheduling system and a
separate ops automation pipeline for another client.
What I can solve for you:
- Repetitive manual workflows turned into reliable automated pipelines
- WhatsApp-based customer communication and lead handling (AI agents,
not scripted bots) - Database-connected AI agents (RAG, live lookups, not static responses)
- n8n workflow design with proper error handling, retries, and
production monitoring — not just happy-path demos
Pricing: Fixed-price from $500 | Open to discussing ongoing retainer
work.
