About this gig

Is your n8n workflow failing, stopping at one node, returning webhook errors, or producing inconsistent results?


I will troubleshoot one existing n8n workflow, identify the actual failure point, and implement a practical fix within the selected package scope.


I can help with:

- broken nodes and expressions

- webhook and trigger issues

- API authentication or mapping errors

- Google Sheets, email, CRM, or database steps

- unreliable routing and missing error handling

- clearer logging and handover notes


You receive a tested result and a concise explanation of what changed. My focus is a stable business workflow, not a vague promise to build an unlimited AI agent.


Please provide an anonymized workflow export or screenshots, the failing input, the expected output, and the relevant error message. Remove credentials and personal data before uploading files.


If the workflow exceeds the package limits, I will define a clear custom scope before additional work starts.

I help small businesses fix the systems that slow them down: messy Google Sheets, broken n8n workflows, unreliable CRM handoffs and repetitive admin work. I have spent 16 years working across sales, operations, CRM and business processes, so I look at both the technical issue and what the team needs day to day. I handle focused, fixed-scope tasks—from Apps Script and API troubleshooting to HubSpot, Zoho and Salesforce fixes—and leave the result tested, documented and easy to use. Send me the current process, the error and your desired outcome; I’ll suggest a sensible first step.
