Lead Generation & Outreach Automation

Find leads, verify them, message them, close them — automatically. A Go-powered scraping + outreach engine that turns 'cold email' from a four-hour ritual into a one-click campaign.

Overview

An end-to-end revenue engine: web scrapers find decision-makers, enrichment APIs verify their contacts, multi-channel campaigns (WhatsApp + email) reach them, and an analytics dashboard tells you what's actually working. 61 API endpoints, one unified workflow.

The Challenge

Sales teams burn 80% of their week on the *finding* part of selling. They build leads in a Google Sheet, copy them into Apollo, paste them into a WhatsApp template, then wonder why nothing converts. The data is stale, the outreach is uncoordinated, and nobody can prove which channel actually drove the deal. Manual lead-gen is a tax that growing companies can't afford to keep paying.

The Solution

I built a Go backend (61 API endpoints) that scrapes target sources, enriches records via third-party APIs, and dispatches multi-channel sequences. A Next.js frontend gives sales teams campaign dashboards, deliverability metrics, and a unified inbox. Deployed via Docker, with healthcare-specific scrapers already running against real BD targets.
