WhatsApp Broadcast Bot Developer — Maintenance & Scaling

I have a working WhatsApp broadcast system built with: * whatsapp-web.js + Puppeteer (headless Chrome) * Node.js / Express.js backend * SQLite database * JWT authentication (admin + client roles) * PM2 process management It's currently running on a Linux VPS with one phone connected. Messages are broadcast via source group forwarding and a web dashboard. What I need: 1. Monitor the bot, fix bugs as they come up 2. Add multi-phone support (multiple bot numbers) 3. Improve session persistence (survive server restarts without re-scanning QR) 4. Add error handling, retry logic, rate limiting 5. Set up HTTPS / Cloudflare tunnel 6. Gradually add more features Requirements: * Strong Node.js and Express skills * Experience with Puppeteer or Playwright for browser automation * Comfortable with Linux server management * Knows SQL/SQLite * Bonus: Experience with whatsapp-web.js specifically To apply: Send me a brief message about your experience with browser automation (Puppeteer/Playwright) and any WhatsApp-related projects you've worked on.
