🎯 Problem Solved: Built an e-commerce platform with abandoned cart recovery system that captures lost leads through WhatsApp rescue popups. 💡 Technical Challenges: Implemented 5 smart triggers (exit intent, 30s timer, inactivity, tab switch, back button) for lead capture. Built backend proxy architecture so Stripe API keys never touch the client (XSS prevention). Integrated Google Sheets webhook for progressive form tracking (started → typing → abandoned → completed). Multi-platform analytics with Meta Pixel + TikTok Pixel + Google Analytics. 🔐 Security: Backend proxy for Stripe, HMAC webhook verification, input sanitization. 📈 Business Impact: Real-time order automation (MAC/PIN → Google Sheets → WhatsApp auto-message), 100% Lighthouse SEO score with Astro SSG, bilingual FR/EN support.
