I will fix, debug and optimize your n8n workflow automation
Bin W
About this gig
Your n8n workflow broke at 2 am again - executions failing, data missing, and no idea which node caused it.
I diagnose and fix n8n workflows properly: find the failing node, fix the root cause (not the symptom), and harden the flow so the same failure doesn't come back.
What I fix most often
- Failed executions and erroring nodes (HTTP, Code, IF/Switch, database and SaaS nodes)
- - Webhook and API issues: payloads, auth, pagination, rate limits
- - Data mapping bugs: expressions, JSON structure, date and timezone mismatches
- - Workflows that only fail sometimes: retries, error handling and alerting added
- - Slow or fragile flows that need restructuring
- How it works
- You send the workflow export (JSON) and tell me what it should do and what it does instead. I reproduce the failure with test data, fix it, and return the corrected workflow with a plain-English note on what was wrong and what changed. Every fix is tested before delivery - you get proof, not promises.
- Message me first with your error message or a screenshot. If I can't fix it, I'll tell you straight - before you pay anything.

Developer-turned-automation-builder. I design n8n workflows that remove manual, repetitive work: lead capture and scoring, CRM sync, notifications, report generation, API integrations. Unlike pure no-code freelancers, I write custom TypeScript/JavaScript code nodes when a workflow needs real logic, so your automation keeps working when templates break. Every delivery includes the workflow file, setup documentation and a walkthrough video.
FAQ
What do you need from me to start?
Export the workflow (top-right menu, Download) and send the JSON, plus what it should do, what it does instead, and any error message. Never send passwords - sample data and test credentials are enough for diagnosis in almost every case.
Which nodes and apps can you fix?
Core n8n nodes, webhooks and HTTP/API calls, Code nodes (JavaScript), Google Sheets, Gmail, Slack, Airtable, databases and most SaaS integrations. If your case is genuinely outside what n8n can do, I'll tell you before you order.
What if the problem can't be fixed?
Then you don't pay for guesswork. I will show you what I found, why it fails, and what your real options are. Message me with the error first - I check every case personally before accepting an order.
Will it just break again next week?
I fix root causes, not symptoms, and where it matters I add retries and error handling. Standard and Premium also add failure alerts, so next time you hear about a problem from your workflow - not from your customers.
Can you also improve a workflow that works but is slow or messy?
Yes. Premium is a full audit: structure, error handling, execution waste and data hygiene, with fixes applied and documented. Standard covers targeted hardening of the flows you rely on most.
