Autonomous AI Agents
AI Lead Engine — Autonomous 4-Agent Pipeline
Autonomous 4-agent outbound system (Alex, Sarah, Marcus, Chloe) that discovers leads from Google Maps, verifies SEO/chatbot gaps, and sends personalized AI emails on autopilot.
Case Study Overview
Value & Architecture Breakdown
1. Problem
Manual B2B lead prospecting, lead audit, and cold email outreach require enormous human labor and deliver poor response rates.
2. Solution
Designed a multi-agent orchestration pipeline using Playwright crawlers, PostgreSQL/BullMQ queue management, and OpenAI cold outreach generation.

System Architecture
Four agents, one pipeline
The system runs as a fully automated pipeline. Alex discovers leads (including social activity checks), Sarah qualifies them, Marcus reaches out via email, and Chloe handles social outreach — all without manual intervention. Each job processes hundreds of leads on a schedule you control.
🔍
1Alex
Lead Collector
Scrapes Google Maps Business Profiles looking for businesses with 1–2 reviews, collects their name, review count, email, website, and social handles. Verifies whether their social accounts are active — checks if they posted in the last 2 days. If a business has a website but no email, Alex scrapes the site to extract it.
100 leads per job · 1–7 concurrent crawlers · Social activity check

2Sarah
Lead Verifier
Takes Alex's leads and verifies each one for SEO readiness, page speed performance, design quality, and whether they have a chatbot. Assigns qualification tags so the right outreach angle is used.

How it all connects
Step 1
Alex crawls GMB for leads + social activity → stores in PostgreSQL via Prisma
Step 2
Sarah verifies each lead → BullMQ queue processes verification jobs
Step 3
Marcus generates + sends emails → OpenAI crafts copy, Nodemailer delivers
LOCKED
Step 4
Chloe sends social DMs → Instagram + LinkedIn outreach (under development)
