Cover image for I developed this project end-to-end

I developed this project end-to-end as a full-stack mobile and web solution. It is a complex multi-store retail system supporting over 100 stores, each with its own products, pricing, categories, brands, and branch-level configurations with advanced filtering and shopping capabilities. The system includes two main platforms: a customer-facing mobile application and a powerful internal management system for employees. Customers can browse products, apply filters, add items to cart, receive personalized discounts, and complete purchases seamlessly. On the internal side, employees manage everything through a mobile-first interface, including POS operations, inventory control, employee scheduling, attendance tracking, salary calculations, performance metrics, and detailed financial reporting (daily, weekly, monthly, quarterly, and yearly). One of the key features is a real-time communication system that includes private and group chat, in-app voice calling, media sharing (images, videos, voice messages), notifications control, and message archiving. The system also supports role-based access control, multi-store management, and integrations with external services to ensure scalability and operational efficiency. The entire architecture was designed for high performance, reliability, and long-term scalability.
