  "account": "Small-scale restaurants face significant revenue losses due to high fees from delivery aggregators. These business owners often lack the resources for complex backend servers and databases to handle orders. To address this issue, I created FoodFlow, an open-source, zero-backend restaurant storefront. It leverages React 19, Tailwind CSS v4, and direct WhatsApp checkout to provide a lightning-fast ordering experience without the need for a heavy server or intricate database.\n\nKey features include:\n1. Zero-backend autonomy - All order processing, item modifications, catalog synchronization, and cart management occur on the client side. The app includes a quick mock setup, requiring only npm install and npm run dev for local development. No configuration or environment variables are needed.\n2. WhatsApp dispatch engine - The app transforms orders into ready-to-send WhatsApp messages, handling delivery vs. pickup options, item variants with mandatory modifiers, and clear pricing with coupons or discounts.\n3. Outstanding performance - The storefront achieves an LCP (Largest Contentful Paint) of under 0.8 seconds on mid-range mobile networks. It also maintains perfect scores in Lighthouse tests for performance, accessibility, best practices, and SEO. It utilizes native inline SVGs with no extra icon dependencies and is built on Tailwind CSS v4 with a comprehensive dark/light theme system.\n4. Modern architecture - The app is built on React 19 and TypeScript 5.9, following strict development guidelines. It utilizes TanStack Query for efficient catalog fetching and caching, along with a lightweight Context API for localized cart management, eliminating the need for heavy state management solutions.\n\nThe MIT-licensed project welcomes feedback on various aspects, such as the separation between TanStack Query and Context, the zero-backend approach for WhatsApp ordering, and experiences with Tailwind CSS v4 in production applications.

  "summary": "Local restaurants—like dark kitchens, pizzerias, and artisan bakeries—are losing up to 30% of their revenue to delivery aggregator commissions. Most of these businesses don't need a heavy, subscription-based backend server or complex database just to receive orders. To solve this, I built and open-sourced FoodFlow : a zero-backend, ultra-fast food ordering storefront built with React 19 and…",
