Refatoração e escalabilidade no QuixAlert!: um projeto de software para monitoramento e gestão ambiental urbana

Abstract

Environmental management in small and medium-sized municipalities in Brazil faces structural challenges, often worsened by the lack of effective communication channels between the population and public authorities. In this context, the QuixAlert! application was developed in the municipality of Quixadá-CE as a digital solution to facilitate environmental service requests and citizen reports. However, its initial implementation with a monolithic architecture presented serious limitations in terms of maintenance, evolution, and scalability. This work presents the software engineering process aimed at the architectural evolution of QuixAlert!, with the goal of transforming it into a more robust, maintainable, and adaptable platform. The adopted methodology is characterized as an applied technological development project, comprising three stages: (1) technical and functional diagnosis of the original version; (2) systematic refactoring to reduce technical debt; and (3) migration to a modular architecture based on native Android (Kotlin), with the addition of new modules. As a main result, a new version of QuixAlert! is expected, with a modular structure, improved security, easier maintenance, and new features. The main contribution of this work is to present a detailed case study on the modernization of a civic software application, demonstrating how refactoring and modularization practices positively impact product quality and enable its strategic scalability.
