About this gig

Is your n8n workflow failing, producing incorrect data or stopping at an API node? I troubleshoot existing automations and explain the cause.


Common issues I fix:

  • Failed nodes, expressions and JSON mapping
  • Webhook triggers and API errors (400, 401, 429)
  • Google Sheets, Drive and Gmail integrations
  • AI nodes returning unexpected results
  • Missing items, duplicates and unreliable runs


How it works:

  1. Send your n8n JSON export (without credentials), the error and the expected result.
  2. I diagnose and fix the agreed issues.
  3. You receive an updated workflow export and a short explanation. Testing requires sample data or suitable access.


Basic: one defined issue in up to 10 steps.

Standard: up to two related issues in up to 20 steps, with basic error handling.

Premium: targeted review, up to three agreed fixes and reliability improvements in up to 30 steps.


New workflows, server administration, ongoing monitoring and third-party API outages are not included.


If the cause is unclear, please message me before ordering. Support in German and English.

Hi, I'm Fabiano, a Germany-based developer focused on n8n automation, API integrations and practical AI workflows. I help businesses replace repetitive tasks with maintainable automations using webhooks, Google Workspace, JavaScript and REST APIs. I also work with self-hosted n8n and Docker. Recent project: an AI invoice workflow that extracts data from PDFs, adds a human approval step and organizes files in Google Drive and Sheets. I provide clear handover notes and communicate in English and German.
