Custom AI Agent Build (n8n + LLM) — Production-ReadySalvador Garibay
Cover image for Custom AI Agent Build (n8n + LLM) — Production-Ready
I build production-grade AI agents on n8n that handle real business workflows — customer service, internal operations, sales support — not demos.
WHAT YOU GET:
Full agent scoping and architecture (use case + tools + memory)
n8n implementation with LLM of your choice (OpenAI, Claude, Gemini)
Custom tools and integrations (CRM, databases, calendars, APIs)
Persistent memory and conversation handling (Postgres / vector DB)
Multi-channel deployment (chat, Telegram, WhatsApp, email, voice)
Error handling, fallbacks, and human-in-the-loop where needed
Documentation and Loom video walkthrough
1 round of revisions after deployment
TYPICAL USE CASES:
24/7 customer service agents with knowledge base access
Internal AI assistants (HR, ops, knowledge retrieval)
Sales agents that qualify leads and book meetings
Voice/SMS agents via Twilio for outbound campaigns
Multi-tool agents that read calendars, update CRMs, send messages
WHY ME:
3 active n8n clients shipping production AI agents
Stack expertise: n8n, OpenAI, Anthropic Claude, OpenRouter, Twilio, Google APIs, Postgres
15+ years in B2B operations (Co-founder & CEO of a $5M MXN/month food export operation to USA/Canada)
MSc in Business Intelligence
I automate processes I actually understand from the inside
DELIVERY: Most AI agents ship in 7-14 days depending on tools and integrations. We'll align on milestones before starting.
LANGUAGES: Spanish (native) + English (working proficiency). Comfortable with written communication and Loom video walkthroughs.
