This work presents Decentralized Vendor Aggregation Platform, a full-stack web application developed to address the lack of dedicated digital infrastructure for the informal home baking sector. The system connects home bakers, customers, and delivery personnel through a unified, role-based architecture consisting of three primary modules: Customer, Baker, and Delivery Person. The platform implements a shared authentication mechanism with role-based access control, enabling seamless navigation across functionalities such as product catalog management, cart-based ordering, secure payment integration using Stripe, OTP-based delivery verification, and real-time geospatial tracking using the Leaflet mapping library. The backend is built using Node.js and Express.js, supported by a structured database managing entities including users, products, orders, and delivery assignments. The system demonstrates a complete end-to-end workflow, from product discovery to verified delivery, validating its feasibility as a functional prototype. While current limitations include randomised delivery allocation and polling-based status updates, the architecture provides scope for future enhancements such as intelligent routing algorithms and real-time communication using WebSockets. Overall, this project serves as a practical implementation reference and architectural framework for digitising small-scale food commerce, ensuring accessibility, transparency, and operational efficiency.
