SuperLemon

Overview

WhatsApp marketing platform serving 20,000+ Shopify merchants across 150+ countries — drives $1M+ in monthly recovered revenue and sends 7M+ messages a month with 12% cart-recovery and 90%+ open rates.

What I did

• Built the SuperLemon Chrome extension that injects Shopify customer, order, and cart context directly into merchants' WhatsApp Web chats — eliminated tab-switching during support and sales conversations
• Shipped extension features — order lookup, customer profile sidebar, abandoned-cart recovery prompts, COD verification flow, and one-click discount codes inside WhatsApp Web
• Architected the React + TypeScript merchant dashboard with Shopify Polaris — segmentation, broadcast campaigns, automated message templates, and analytics
• Integrated WhatsApp Business API with Shopify webhooks for real-time order notifications, abandoned-cart triggers, and shipping updates
• Optimised extension for performance and security — minimal DOM injection footprint, scoped permissions, and Chrome Web Store policy compliance

Outcome

Helped scale the platform to 20,000+ merchants generating $1M+ in monthly recovered revenue across 150+ countries.
