Integração móvel-servidor: práticas e implementações de aplicações modernas

Abstract

This study aims to present, through a qualitative approach and action research, the practices, technologies, processes, and challenges involved in the development of modern mobile applications integrated with cloud-based servers. Based on the author's professional experience as a software developer, the research analyzes the integration of Android and iOS applications with back-end services built using NestJS and TypeScript, deployed on AWS and Azure infrastructure. The justification for the study lies in the growing demand for scalable, secure, and maintainable mobile solutions, which require well-structured architectures such as REST, GraphQL, and Clean Architecture. The adopted methodology included practical observation, hands- on experience in real-world projects, and the use of tools such as Jira, Docker, Bitbucket, and messaging systems like RabbitMQ. The results highlight clear advantages of adopting modular architectures and agile practices, such as increased maintainability, code reuse across platforms, reduced time-to-market, and improved delivery quality. Conversely, challenges were identified related to training time and team learning curves, particularly during the transition to Clean Architecture and the mastery of new messaging and automated testing tools.
