Project Title: Autonomous Lead Intelligence & Email Verification Pipeline
Tech Stack: n8n | JavaScript (Node.js) | Google Sheets API | REST APIs | Regex
The Challenge
Manual lead generation is slow and often results in "dirty data" (duplicates, junk emails, or dead links). The goal was to build a system that could autonomously find, verify, and organize B2B contact data with zero human intervention.
The Solution (The n8n Engine)
I engineered a multi-stage automation pipeline that runs on a schedule to harvest and clean business data. Key technical features include:
Intelligent Data Scrubbing: Built custom JavaScript nodes to filter out "junk" emails (like Sentry logs, tracking pixels, and support aliases) using advanced Regex and domain blacklisting.
High-Volume Batch Processing: Implemented a Split-in-Batches loop with a recursive feedback mechanism. This ensures the system processes thousands of rows without hitting API rate limits or crashing.
Anti-Bot & Rate-Limit Handling: Configured intelligent "Wait" states and HTTP request retries to mimic human browsing patterns, ensuring high success rates when scraping site data.
Automated Data Integrity: The system automatically identifies duplicate URLs, verifies the existence of a business website, and updates a "Scrape Status" column in real-time so users can see exactly why a lead was qualified or rejected.
Key Results & Impact
100% Autonomous: Operates on a 45-minute trigger, requiring zero manual oversight.
Data Purity: Automatically removes 95% of non-functional or "junk" contact info before it reaches the final database.
Efficiency: Processes up to 100 leads per run, turning a week's worth of manual searching into an hour of automated work.
