Built a self-hosted n8n pipeline that pulls leads from 5 sources (lead database, Google Maps, LinkedIn, job postings, growth signals), then normalizes, dedupes, enriches and verifies them, scores each lead against an ICP rubric, uses an LLM for company research and personalized emails, and sends from 5 inboxes via a round-robin queue. Supabase/PostgreSQL as the source of truth, Discord alerts for the team.
