Diseño e implementación de una plataforma web para la oferta y contratación de servicios independientes con verificación de proveedores

Abstract

During the project, how independent services are offered and demanded in Cuenca will be analyzed. It was discovered that many people rely on recommendations, messaging groups, and public advertisements, which do not always provide enough information about service providers. Therefore, ServiLink, a web platform for posting and hiring independent services with provider verification, was developed. This research adopted a quantitative approach, and the development was organized using Scrum in seven two-week sprints. During the requirements analysis, 21 functional and 19 non-functional requirements were established and documented in an SRS and 20 UML diagrams to define the architecture, database, and interface. The platform was built using Node.js, Express, and MongoDB on the server side, and React.js, Vite, and Tailwind CSS on the client side. Role-based authentication, documentary verification of providers, advertisement posting and search, request management with appointment proposals, and automated notifications via the WhatsApp Business Cloud API were implemented. The system was validated with 24 functional test cases, yielding 24 PASS and 0 FAIL results (100% test coverage), and was deployed to production using Railway. The results show that ServiLink meets the objectives and can contribute to reducing the informal hiring of independent services in Cuenca.
