Product Verification QR Scanner App

@AwaisChaudhry

Hello, I will build a cross‑platform barcode scanner app for iOS and Android that determines Halal/Haram/Doubtful status based on ingredient data, with product images, ingredients, and allergen info pulled from supermarket sources. It will scan EAN/UPC codes, perform product lookups with rich details, and explain decisions at the ingredient level. A backend will manage product data, ingredient rules, and a coin system (new users receive 100 coins, 10 coins per scan) with a clean history UI. Data ingestion will support multiple sources with reliable caches, and rules can be updated remotely without requiring app updates. The stack will be Flutter or React Native for rapid cross‑platform delivery, with a backend API and admin tools to adjust rules and coin logic. Deliverables: mobile apps (iOS/Android), backend services, source code and basic docs. I estimate 1250 AUD with a timeline of about 5 weeks, including milestones and documentation. Where should the data be sourced from, and are there preferred supermarket APIs or partners? Which tech stack do you prefer for the app (Flutter or React Native), and any backend preferences (Firebase, Node.js, Python)? How should ingredient rules be updated remotely without app updates (admin UI, webhooks, or CDN)? What security and privacy requirements apply to user accounts and the coin system (auth providers, data retention, GDPR)? What are your expectations for localization, accessibility, and compliance testing across iOS and Andro

Hi, I’m an experienced mobile developer with strong expertise in Flutter/React Native and building cross-platform apps with backend integration. I’ve worked on barcode scanning apps and API-driven product databases, including image retrieval, ingredient parsing, and user point systems. For your app, I can implement: EAN/UPC barcode scanning with real-time product lookup Ingredient-level classification (Halal, Vegan, Kosher, Doubtful) Coin-based user system with scan history Backend management for products, rules, and user accounts I can provide a clear plan for sourcing supermarket product data and updating ingredient rules without app updates. I’ll also deliver full source code, documentation, and support for deployment on Android & iOS. Happy to discuss timeline, cost, and share relevant past work. Thanks

Hi, this is Elias from Miami. I read your scope and I understand you want a barcode scanner app (iOS + Android) that scans EAN/UPC, pulls product image + ingredients + allergens from online sources (including supermarkets), then classifies the product as Halal / Vegetarian / Vegan / Kosher / Doubtful with ingredient-level explanations. You also need accounts + a coin system (100 start, 10 per scan), scan history, and a backend where ingredient rules can be updated without publishing a new app. How I’d build it * App: Flutter (fast cross-platform) with camera barcode scanning * Data sourcing: start with reliable public databases (Open Food Facts, GS1-style datasets where accessible), then add supermarket-specific sources via official APIs/feeds when available. If a supermarket has no API, we can’t reliably scrape at scale, so I’d propose a supported-source list for v1 and expand. * Backend: Node + PostgreSQL for users/coins/history, plus a rules engine (ingredient rules in DB) and an admin panel to edit rules live * Classification: rule-based first (auditable), with “doubtful” when data is missing/ambiguous, and clear explanations per flagged ingredient Q1: Which countries/supermarkets must be supported on day one? Q2: Do you want kosher/halal to be strict certification-based, or ingredient-based inference only (with a confidence label)? Q3: Are users allowed to submit corrections/photos when a product is missing or wrong? Regards, Elias

@Herculesz

Hi I can build your cross-platform barcode scanner app with fast EAN/UPC scanning, supermarket data lookup, and a full ingredient-classification engine for Halal, Vegetarian, Vegan, Kosher, and Doubtful categories. The main technical challenge is sourcing consistent ingredient data across supermarkets and mapping each ingredient to a dynamic ruleset, and I solve this using API aggregation, structured fallbacks, and a backend rules engine that updates without requiring app releases. The mobile app will be built in Flutter or React Native with clean UI, product images, allergen details, scan history, and your coin-based system (100 coins on signup, 10 coins per scan). The backend will manage product ingestion, rule updates, classification logic, and user accounts in a secure and scalable way. I have experience with barcode scanning libraries, product APIs, and controlled ingredient-rule mapping. You’ll receive full source code and clear documentation. Thanks, Hercules

Hello, we can develop a cross-platform barcode scanning app for iOS and Android that identifies whether products are Halal, Vegetarian, Vegan, Kosher, or Doubtful by analyzing ingredients, allergens, and product data sourced from supermarkets and online databases. The solution will include fast scanning, clear ingredient-level explanations, user accounts with a coin-based scan system, scan history, and a clean, user-friendly interface. The backend will manage product data, ingredient rules, and coin logic, with the ability to update rules without requiring app updates. I’ve recently developed a product verification web application, so I’m familiar with the challenges around data accuracy and management. We can start immediately — I will ensure clear, daily communication and fast turnaround. You’ll always know the exact progress. Lets connect over chat so we could discuss the details.
