A fully automated lead capture and qualification pipeline that receives form submissions, processes them through AI scoring, logs every step to a database, and fires Slack alerts on failure — with retry logic and a real-time monitoring dashboard. Architecture Tally Form → n8n Webhook → Map Form Fields → Send to Supabase → Check Request → Slack Alert (on failure) → Hubspot Dashboard Key Engineering Features • Webhook endpoint receives and maps Tally form fields in real time • AI qualification via Claude — scores each lead 1-10 with reasoning • Structured logging to Supabase workflow_logs table (step name, status, timestamp, metadata) • Error detection with If node — routes failures to Slack alert branch • Retry logic with exponential backoff (3x: 2s / 4s / 8s) before alert fires • Idempotency check prevents duplicate lead entries on repeated submissions • Real-time dashboard showing leads, qualification rate, failed workflows, active alerts
