I will review one existing n8n workflow and one clearly defined reliability issue.

The service includes: • tracing the affected trigger, data mapping, and execution path • checking validation, duplicate handling, API or webhook behavior, and failure handling where relevant • identifying the likely root cause or material reliability risk • implementing one small, bounded fix when technically feasible • testing the affected path with synthetic or client approved sample data • providing a short diagnostic summary, test evidence, known limitations, and handoff notes

This service does not include a full workflow redesign, AI scoring, CRM synchronization, scraping, outreach, high scale architecture, exactly once guarantees, ongoing monitoring, credential custody, or work outside the agreed issue. Credentials remain in the client’s own environment.
