About this gig

Your n8n workflow was working, then it wasn't. A node started failing, a trigger stopped firing, or an API changed and broke the chain, and now the whole automation is stuck.


Built by someone else and now acting up, or your own workflow grown too tangled to debug? I read through it, find exactly where it's breaking, and fix it: a bad node config, a broken credential, a webhook that stopped firing, or logic that never handled an edge case.


What you get:

Root-cause diagnosis, not a guess

Node, credential, and webhook fixes

API and HTTP request error handling

Cleaned-up logic where that's the problem

A short note on what broke and why


If your workflow needs a rebuild, not a fix, I'll say so upfront rather than patching something that breaks again next week.


How it works:

Send me the workflow export or share access, plus the error

I diagnose and confirm the fix before touching anything

I fix it, test it, hand it back working


I also build new automations, AI voice receptionists, and booking assistants if you need more.


Send your workflow and the error first.
