Práticas e tecnologias utilizadas no desenvolvimento de APIs para soluções mobile na empresa Avenue Code

Abstract

This report presents the activities carried out during the period of work as a backend developer at Avenue Code, a multinational company specialized in software engineering consulting and digital transformation. The activities were developed in an automotive sector project, whose main objective was the development of scalable backend APIs responsible for providing resources and functionalities for corporate mobile applications aimed at vehicle owners. These APIs acted as an intermediary layer between the applications and the automaker's internal systems, enabling the secure integration of vehicle-related data and services, maintenance scheduling. service tracking, real-time notifications, and other personalized interactions with the end customer. The main focus of the work was to ensure that these communication interfaces were robust, high-performing, and easily evolvable, guaranteeing the availability and reliability required in an environment with a high volume of access and multiple integrated systems. The relevance of this work lies in the need to modernize existing systems, seeking greater efficiency, availability, and scalability of the services offered to end users. The tasks performed included the development, maintenance, and support of microservices using Java and Spring Boot, with data persistence in a MySQL database and asynchronous communication through AWS services such as SQS, ECS, and EKS. The methodology adopted was based on agile practices and microservices architecture principles, emphasizing continuous integration, automated testing, and deployment in a cloud environment. As a result, more robust and scalable systems were delivered, with improvements in service integration and a reduction in application response time. Furthermore, relevant knowledge was acquired in cloud architecture, container orchestration, and asynchro- nous messaging patterns. It is concluded that this experience significantly contributed to the enhancement of technical skills and to the consolidation of knowledge related to contemporary software engineering practices in large-scale projects.
