Onde Tem?: uma ponte digital entre o consumidor e o comércio hiperlocal

Abstract

Digital transformation has widened the competitive disadvantage between large companies and small local businesses, which often face technical and financial barriers to entering the digital landscape. At the same time, consumers increasingly seek immediate solutions to their needs, a demand that is poorly met by the long delivery times of traditional online commerce, even though desired products are often available nearby. This work addresses this gap by proposing the development and evaluation of “Onde Tem?”, a hyperlocal marketplace ecosystem designed to act as a digital bridge between consumers and local commerce. The developed solution consists of two main components: a native Android client application and a web-based dashboard for vendors and administrators. The system architecture is based on the BaaS paradigm, using the Firebase platform to manage real-time data synchronization, user authentication, and media storage. The client application was developed in Kotlin using Jetpack Compose, while the web dashboard was built with React and TypeScript. Usability evaluation was conducted through asynchronous task-based tests with two distinct groups of participants (consumers and local merchants), complemented by the SUS questionnaire. The results indicated “Excellent” usability for both platforms, with average SUS scores of 87.5 for the client application and 82.0 for the vendor dashboard. Qualitative feedback validated the platform’s value proposition, highlighting its practicality for consumers and its low entry barrier for merchants. Therefore, this work contributes a technically viable and relevant architectural model for hyperlocal marketplaces, demonstrating the potential of modern technologies to strengthen the local economy and optimize the consumer purchasing journey.
