Four internal technical proofs for reliable lead intake and CRM data quality are now in my portfolio. 1. Lead intake and human review: validation, normalization, structured summaries and reply drafts, with sensitive sending kept under human approval. 2. Persistent deduplication: repeated events and normalized identities checked with native n8n Data Tables, including a verified process restart. 3. Fail-safe processing: an unsafe phone-normalization assumption repaired and preserved as a regression case; the revised synthetic suite passed 9/9 tests. 4. Workflow QA: import/export, real n8n runtime checks, webhook tests and persistent-state verification. The examples use synthetic data and are labeled as internal technical proofs. Client production experience and commercial results remain unverified. I am offering a bounded Lead Intake Reliability Sprint. Scope, timing and price are agreed before starting; production activation requires a separate approval.
