I built a self-healing B2B lead ingestion pipeline with n8n, PostgreSQL, and JavaScript. It uses a dead letter queue, rate-limit backoffs, and pre-flight schema gates to prevent silent lead loss and retain data during upstream API outages.
In my CRM webhook orchestrator, I implemented HMAC validation and transformations to deduplicate incoming leads. I also developed an n8n multi-agent AI engine with PII sanitization and model fallbacks to reduce LLM costs while protecting customer data.
