Message Queuing Telemetry Transport (MQTT) is widely adopted in these environments for its lightweight design, requiring minimal resources and optimizing network bandwidth. However, it still faces performance issues due to TCP and Transport Layer Security (TLS) overhead. Quick UDP Internet Connections (QUIC) has emerged as a promising alternative to improve communication performance. However, existing performance studies lack evaluations of MQTT over QUIC under low latency and unstable network conditions. This paper compares the performance of MQTT over QUIC, TCP, and TCP+TLS in a virtualized IoT environment. The performance evaluation follows a well-established approach and analyses latency and connection establishment time as key metrics under stable and unstable conditions. Results highlight the potential of QUIC as an efficient and secure alternative for IoT communication.

The problem lies in the complexity and high cost, which limits access to this technology, especially for small and medium-sized enterprises. Therefore, the objective of this work is to propose the development of a service platform for recording and analyzing user interactions in digital environments, known as clickstream, that is accessible and easy to integrate, eliminating the need for companies to build an infrastructure from scratch. To achieve this objective, the methodology was based on three main components: a Kafka Topic Management Infrastructure, a Template for Integration with front-end Applications, and Detailed Documentation. As a result, the platform, named MG-ClickStream-Manager, was developed to enable the collection, processing, and analysis of click events, facilitating data-driven decision-making. In conclusion, the project shows potential to simplify implementation and democratize access to clickstream analytics, allowing developers to focus on analysis and decision-making without worrying about infrastructure complexity, thus promoting a more efficient development ecosystem.

Considering the growth of literary content consumption on mobile devices and the expansion of online reading communities, the project proposed a technological solution that integrates reading, interaction, and visibility within a single environment. The development was carried out using React Native, TypeScript, and Expo, adopting a layered architecture with separation between interface, state management logic, services, and visual standardization. Global state management was implemented through the Context API, combined with a unidirectional data flow to ensure structural organization and predictability. UX/UI, usability, and accessibility principles were also applied. The process was guided by the Scrum framework, allowing the iterative and incremental evolution of functionalities. As a result, a functional mobile application was developed, featuring multiple screens, API integration, real-time communication, and a modular architecture aligned with best practices in mobile development.

This report aims to describe the software development and registration process for the Improov application, which was created using the PHP programming language, the Laravel framework, MySQL database, and integration with the Github API, as a prerequisite for obtaining a degree in Internet Systems Technology. During the course, we developed a project aimed at assisting the self-directed learning of beginner students in the technology field through a gamified platform. During development, we contributed to several stages of the process, such as: target audience analysis and research, prototyping, layout and source code development, and software deployment on a cloud platform service.
