About this gig

Is your n8n workflow failing, stopping at a node, or returning API errors? I diagnose the cause and repair existing automations so your business process can run as intended.


I help founders, operations teams, and agencies who rely on an active workflow and need to unblock lead routing, data transfer, notifications, or AI steps without rebuilding everything from scratch.


I inspect execution logs, node inputs and outputs, expressions, credentials, HTTP responses, webhook payloads, and data mappings. Depending on the agreed scope, I fix the faulty node or request, correct data handling, add practical error handling, and retest the affected path.


You receive the repaired workflow, a concise root cause summary, test notes, and practical steps to reduce repeat failures. I work from a safe export or copy where possible and never change a live system without approval. Third party outages, expired credentials, API limits, and inaccessible services may need your action.


Send a redacted workflow export, the exact error message, what should happen, what happens instead, and your deadline. I'll confirm feasibility and scope before you order.
