Project Overview
Dudh Sathi is a comprehensive dairy management mobile application designed to revolutionize the traditional milk delivery system. The app addresses critical challenges faced by dairy cooperatives, delivery personnel, and customers in managing daily milk distribution operations.
The application serves three primary user types: Customers who order and receive milk, Delivery Personnel who manage routes and deliveries, and Admin who oversee operations and analytics. Built with React Native for cross-platform compatibility, the app ensures seamless performance on both iOS and Android devices.
The core problem we solved was the inefficiency of manual record-keeping, which led to billing errors, delivery disputes, and lack of transparency. Dudh Sathi digitizes the entire workflow from order placement to payment processing, providing real-time updates and automated calculations.

Challenges & Solutions
Challenge: Offline Functionality
Delivery personnel often work in areas with poor network connectivity. We implemented Redux Persist with AsyncStorage to cache data locally, allowing the app to function seamlessly offline and sync when connectivity is restored.
Challenge: Real-Time Location Updates
Continuous GPS tracking drains battery quickly. We optimized location services using geofencing and adaptive location update intervals based on movement speed, reducing battery consumption by 60%.
Challenge: Complex Billing Logic
Different pricing tiers, discounts, and subscription models required complex calculations. We built a flexible billing engine using Firebase Cloud Functions that handles all edge cases and ensures accurate monthly statements.
Challenge: Multi-User Role Management
Three distinct user types (Customer, Delivery, Admin) needed different interfaces and permissions. We implemented role-based access control with Firebase Security Rules and created modular UI components for each user type.
