Experienced n8n Developer Needed for Workflow

Hi, I’m looking for an experienced n8n developer who can help me finish a workflow for my app. The workflow is simple on the surface, but I need someone reliable who understands n8n very well and can prepare it for future automation tasks.

The main goal right now is to set up a workflow that takes data from a trigger, formats it, and sends it into Google Sheets. The structure is:

Manual Trigger (or future webhook trigger)

Set Node (format fields)

Google Sheets (append row)

I already started the workflow but I want a professional to finish it correctly, clean up any issues, set up the credentials properly, and make the workflow ready to expand later.

What I need from you:

Build or fix the workflow inside n8n

Connect Google Sheets and test row insertion

Make sure the Set node and field mapping are correct

Clean, organized node structure

Add basic error handling (so nothing breaks silently)

Short explanation of what you built so I can maintain it later

(Optional but appreciated) Add a webhook trigger for future app events

Requirements:

Proven experience with n8n

Understanding of Google Sheets API

Ability to troubleshoot credentials and data mapping

Good communication
