About this gig

Is your n8n workflow failing, timing out, sending wrong data, or breaking after an API change? I'll find the root cause, fix it, test it, and explain exactly what I changed.


I come from a backend engineering background, so I don't just patch the visible error. I trace the problem through your nodes, HTTP requests, webhooks and code, then add error handling so it doesn't break again.


I can fix:

- Failed executions and stuck workflows

- Webhook, HTTP Request and API/authentication errors

- Data mapping, IF/Switch and Code node problems

- AI agent workflows (OpenAI, Claude, Gemini)

- Google Sheets, Airtable, CRM, Slack, email and WhatsApp integrations

- n8n cloud and self-hosted (Docker) setups


You get:

- A working, tested workflow

- A short summary of what was wrong and what I changed

- Notes to prevent the issue in future


Message me before ordering with your error screenshot or execution log and I'll confirm the right package.

I'm an n8n and AI automation engineer with a Master's in Computer Science and 5+ years of backend development. I build n8n workflows, AI agents (OpenAI, Claude, Gemini), API integrations and webhooks, and I fix broken workflows. Coming from backend engineering, I add custom code, error handling and clean structure so your automations keep running. I also create AI automation tutorials online. Message me your workflow and I'll reply with a clear plan and quote.
