Technical Architecture & Execution:
• Headless Google Sheets Engine: Connected the frontend directly to a structured Google Sheets backend via REST APIs, allowing the client to update stock, seasonal honey harvests, batch ghee pricing, and promotional banners in real time without redeploying code.
• Lightweight & Dependency-Free UI: Built with Vanilla JavaScript, semantic HTML5, and modern CSS to deliver sub-second mobile load speeds and zero third-party framework overhead.
• Conversational WhatsApp Order Routing: Implemented dynamic cart state management with one-click WhatsApp routing, automatically converting cart selections, item weights, and total values into a pre-formatted, error-free order message.
• Dynamic Filtering & Pack-Size Selectors: Built instant client-side category sorting (Ghee, Honey, Dry Fruits, Cold-Pressed Oils) and responsive pack-variant selectors for swift customer checkout.
