The proposed solution adopts a modular monolith architecture with strong adherence to Hexagonal Architecture principles, promoting a clear separation between business logic and external dependencies. Furthermore, the system incorporates concepts of Event-Driven Architecture, enabling asynchronous processing of critical tasks through distributed messaging, which enhances scalability and resilience. To support performance, in-memory caching technologies and state management strategies are employed, reducing latency in critical operations. Additionally, the system leverages geospatial indexing based on H3 to optimize the delivery dispatch process, enabling efficient proximity queries. The adopted methodology is based on the definition of functional and non-functional requirements, domain-driven design modeling, and incremental implementation using containerization to ensure environment consistency. The results indicate that the solution is capable of handling high-demand scenarios, providing adequate performance, architectural organization, and ease of evolution. It is concluded that the combination of clean architecture, asynchronous processing, and geolocation techniques constitutes an effective approach for building modern delivery systems, serving as a solid foundation for both real-world applications and academic studies.

The aim of this system is to monitor the process of managing and enrolling in elective components, providing data control. Currently, teachers manually register students on an informal document and then the list of those registered is sent to the school office. The platform has functions for the administrator, who will manage the system, as well as for the students, who will use it to register for electives. The administrator has access to the following functions: insert, list, edit, archive semesters, electives, teachers and students, as well as generate enrollment reports. The interface for students aims to simplify and facilitate the process of registering for electives, allowing students to view the options available for choosing electives. The software's contribution is to enable students to register autonomously. The main technologies used to develop the platform were Java, Spring Framework, Thymeleaf, PostgreSQL, HTML, CSS and JavaScript.

These innovations are lar gely driven by the growing population of cities and the high degree of urbanization seen today. However, such changes often occur rapidly and without proper planning, resulting in a lack of effective control and causing harm to both the environment and the population. To improve the control and management of urban environmental threats, the development of software was pro- posed to map, store, and document as many of these threats as possible, based on community input. The system aims to enhance safety and quality of life for people living in affected areas by enabling residents to actively participate in identifying and mapping local risks. The case study selected was the city of Cajazeiras, located in the interior of the state of Paraíba, Brazil, where the main environmental threats were identified and categorized. The system operates through two main modules: (1) a mobile application that allows the public to report threats— such as landslides, flooding, air pollution, illegal waste disposal, or soil erosion—according to specific categories; and (2) a control panel for public administration to manage these reports, including geolocation data, and prioritize mitigation efforts based on the severity and impact of each threat. This approach aims to foster a more efficient and collaborative management of urban threats, making the city more resilient to environmental challenges. However, it is im- portant to note that collecting information on the system’s usability was not within the scope of this project. Nonetheless, the entire development process was guided by feedback from envi- ronmental and administrative management experts from the city of Cajazeiras. From a technical perspective, the system— named Cidade Monitor—was developed using a simple and scalable architecture, with a focus on code optimization and software development best practices. The platform is expected to support environmental management in any city where it is implemented, promoting collaboration between the population and local authorities in tackling urban threats.
