I will build, fix and optimize n8n automation workflows and ai agents
Saul Zambrano
About this gig
Broken n8n workflow? Repetitive tasks eating your week? I build and fix n8n automations and AI agents that keep working in production, not just in the demo.
WHAT I DO
- Fix errors: failed nodes, credentials, webhooks, data mapping, loops
- Build custom workflows: CRM, Google Sheets, email, forms, webhooks, any REST API
- AI agents with memory and tools (OpenAI, Claude, Llama) for support, lead qualification and content
- Error handling and instant failure alerts, so nothing breaks silently
WHY ME
- Computer Engineer with 6+ years in performance marketing: I automate with business results in mind
- I run n8n AI agents in production with memory, model fallback and human handoff
- Clean, documented workflows you fully own (JSON export)
HOW IT WORKS
- Send your goal or the failing workflow (JSON or screenshots)
- I confirm the scope before starting
- You get the working workflow, the JSON export and clear setup notes
Not sure which package fits? Message me before ordering and I'll recommend one.

FAQ
Do you work with n8n Cloud or self-hosted n8n?
Both. I can work inside your n8n Cloud or self-hosted instance, or build it in mine and hand you the JSON file to import.
What do you need to fix my workflow?
The workflow JSON export (or user access to your instance), screenshots of the error and a short description of what it should do.
How do I share access safely?
Invite me as a user to your n8n instance or create temporary API keys. Never share your main passwords; you can revoke access after delivery.
Can you connect an app that has no n8n node?
Yes. If the service has a REST API, I connect it with the HTTP Request node and handle authentication, pagination and errors.
Which AI models do you use for agents?
OpenAI, Claude, Llama (via Groq) or Gemini, depending on your budget and quality needs. AI usage is billed to your own API account.
Will I own the workflow?
Yes. You receive the JSON export and full documentation. It is 100% yours to use and modify.
Do you offer support after delivery?
Yes. Revisions are included in every package. For ongoing changes or monitoring after delivery, message me and I'll send you a custom offer.
I use Make or Zapier. Can you help?
My specialty is n8n. I can rebuild your Make or Zapier scenario in n8n, which often reduces monthly costs.
