I decided to approach this differently by leveraging modern AI technologies. I spent time learning the strengths of various LLMs (Grok, DeepSeek, ChatGPT, Claude 3.7) and combined the best aspects of each for my solution.
The technical challenges were substantial. To reach 1B+ verified contacts, I had to:
- Implement residential proxy networks using Luminati/Bright Data, with Node.js for connection management and Redis for IP rotation scheduling
- Develop captcha-bypassing systems combining Puppeteer's browser automation with 2captcha API integration and custom computer vision models using TensorFlow
- Perfect web scraping at scale with Python (Beautiful Soup, Scrapy), optimized with asyncio for concurrent execution, and Playwright for dynamic content rendering
- Build a robust backend infrastructure using Laravel PHP framework, vanilla JavaScript for lightweight frontend interactions, and PostgreSQL for storing the structured data with proper indexing
I hope you enjoy using the trial, I made it especially for you guys.
